How to calculate the square meter of the wall. How to calculate the area of the room

Continuing the repair work, the question arises: how much is the square meter required for the covering material.

So to spend extra money, go to a better square meter counting room to start production and only then go to the store with specific requirements.

On packages with paint, plaster, primer is essentially marked, on which the size of the room is calculated by a given amount of mixture.

The main question is how many packages or cans are needed in an adequate wall or floor area.

What is a square meter

First you need to decide what the square meter is. Those who were poorly taught in school mathematics still face the problem of calculating the number of building materials easily or later. So the square meter is the main point of reference when determining the area of ​​the room.

If you draw a square (this is a geometric shape with the same sides), and the side is 100 cm. Will be, then when multiplied, we get the number 10,000 cm. This means that the size of this figure is 10000 cm. Is 2. It's as simple as possible. Calculate in meters: 100 cm. Is 1 meter. We apply the calculation formula of this area - we rotate the two sides, then we increase by 1, we get 1 meter. Therefore, the size of the square is 1 square meter.

Square meter counting equipment

For calculation, it is necessary to prepare a calculator.

If it is not, then the multiplication table on a normal notebook for first graders.

If the walls have 2, not 3 meters, but, for example, 2.5 meters, then it is still better for a calculator. This is a very complex load for the brain, which is not used to deal with numbers.

It is advisable to keep a piece of paper on hand and handle it for recording.

It is necessary to measure with a roulette or centimeter.

Square meter calculation formula

To calculate the area, you need to apply the square meter formula A x B, where the number is the length of one side, and the length of the other side. Floor or wall shape or wall if they can be identical.

Often it is not a square, but a rectangle, that is, the number will have one value in it, and the number is another. They will need to be multiplied in mind, either on a multiplication table or on a calculator. And the resulting number will be an area that will need to be covered with paint or something else.

It happens that the shape of the floor is not standard, but, for example, trapezoidal. Then it is more difficult, especially for those who do not know what a triangle is (this is also in nature). To calculate the size of a trapezoid, it is necessary to first calculate the area of ​​the rectangle in the middle, then the intensity of each triangle on the sides, then these three numbers. Lays. Isn't it easy to tell the workers' brigade immediately? They think how to calculate the square meters of the room.

Important! If a misunderstanding arises at this stage, it is better to immediately call the math teacher and ask him to calculate, how many square meters. M It has room.

Floor area or ceiling

The ceiling and floor are the same in a typical apartment. How to calculate square meters? Very simple. If indoor indoor, there is no roof - there are only genders and walls.

Stage # 1. Measure the length of the room and write the resulting number on a piece of paper. If the number is an integer, we will write only one digit. For example, 5 (m). If the number is greater than 5, but less than 6, you must memorize and write the decimal fraction, for example, 5.5 (m).

Stage # 2. Measure the width of the room and record evenly. For example - 3 m.

Stage number 3. Now it is necessary to multiply these two numbers. Example: 5 x 3 00 u003d 15m. Therefore, the floor area is 15 square meters. As a result, the ceiling size will also be 15 square meters. like this. Record this number separately and break the handle.

Square Solid Wall

How to Calculate Quadrasura Solid Wall? As we have measured the floor or ceiling. The algorithm of action is the same when calculating the size of the floor:

Measuring and writing the length of the wall;

Measuring height;

Multiply the two numbers - the result and the desired square meter.

Example: 2.20 m, length 7 m height. 7 x 2.2 00 u003d 15.4 m. Wall area - 15.4 square meters. like this.

How to calculate a square meter wall with windows

It will be more difficult to deal with the wall on which the window is located.

Algorithm of actions:

This view has already been passed to calculate the wall size. Give a known number to an already known number - 15.4 m2.

Next, measure the height and length of the window. Multiplication numbers. For example: length 1.5 m, height 1.2 m. If multiplied, it comes out to 1.8. Therefore, the area of ​​the window is 1.8 square meters. like this.

We take the wall area and reduce the size of the window: 15.4 - 1.8 u003d 13.6. The area that will need to be placed in order - 13.6 square meters. like this.

Important! Be sure to record and circuit the figures obtained with the handle while calculating so as not to get lost in our own calculations.

How to calculate a square meter wall with a door

When necessary calculate the same square meters to produce walls with doors. If from a mathematical point of view the door of a gate is a simple rectangle, we calculate its area with the general formula one x. That is, it is necessary to measure the height and length, then multiply and multiply the size of the door.

Next, from the wall area, we subtract the size of the door and get the square in which the final material will need to be purchased. If the previous owner of the apartment built a door with an arch, this cannot be done here without calculating the size of the circle.

Measure the complex shaped area

Circles and triangles - complex bases for self-calculation. How to measure a square meter of circumference if there is no mathematical or engineering education? Again, according to the formula.

How to measure the size of a circle

There is a formula for calculating the area of ​​a circle. There is a constant number - the ratio of the length of the circumference to its diameter. It is the same for all sizes of circles. It's called pie and is equal to 3.14. This is the number and use when calculating.

Stage number 1. Measures the diameter (this is a line that passes from the center of the circle to the other part). Let the diameter be equal to 3 meters. Next, we find the radius - this is half the length of the diameter. It is 1.5 meters. We write the radius on the paper.

Stage no. 2. We produce calculations according to the formula S \ u003d PR 2, where S is the area of ​​the circle, P is a constant number, and R is the radius of the circle. It is 3.14 x (1.5 x 1.5) 7 u003d 7,065. The area of ​​this circle is 7,065 square meters. like this.

But this is an area of ​​a perfect circle. The arch above the door is semicircular. So, you still need to divide the two numbers and add more to the rectangular area of ​​the door. 7,065: 2 3.5 u003d 3.53 m2.

How to measure the area of ​​a triangle

If the previous owner of the apartment was a mathematician, he could well make a triangular shape on the roof, which needs to be restored and allocated another color or plaster. You have to consider not having too much money.

The calculation of square meters begins with a careful observation of this figure in a triangular figure.

It is necessary to find the base of the triangle, that is, the line on which the other two (such as the roof is on the house). Next, spend a line from the opposite top to the base. Record these two numbers.

Stage no. 1. Divide the base of the triangle by 2 and write. This number will come in handy in the near future. Measure height and also write.

Stage No. 2. Production Census M 2. Statistics. To do this, it is necessary to use the formula: s \ u003d 0,5ah, where S is the area of ​​the triangle, and the base, and H is the height. Example: Base 3m, height 2.5m. Total: 0.5 x 3 x 2.5 00 u003d 3.75. Triangle size - 3.75 m 2. Don't forget the error.

Tip! When calculating it is better to invite another person to help. One head is better, and two are more reliable.

This case is for small - go to the store and buy stuff. Here you still have to consider, as not all packages are designed for large rooms. For example, the ceiling size in the kitchen is 3 x 3. How many square meters of plaster will be needed if a package can be covered with 3 square meters. like this? We assume: the size of the roof is 9 square meters. like this. One package takes 3 square meters. As a result, there are 3 packs for the entire roof.

If the package states that the cost is 12 square meters, it means how much material is needed to cover the wall with a size of 3 x 4 meters.

Or another example. At wall 6 in the apartment 4. How many square meters need to be painted? Multiply 6 by 4, we get 24 square meters. This is how much if each bank used 6 square meters you need a can of paint for 3 liters. like this? We assume: 24 dilim 6. It comes out 4. So you need to buy 4 three-liter cans of paint to cover the entire wall.

For repair work, it’s always best to take a little more stuff so you don’t go back to the store later. In the future, if you have something to cut or pick, the remnants of the material may be healthier.

Why you need to know the floor area

Definition of the area of ​​a rectangular area

Wrong plan calculation of room square

Learning the area of ​​a triangular room

How to calculate the area of ​​the room

Proportion between floor and windows

It is impossible to repair the outdoor surface, do not know the exact floor area in a private house or apartment. The fact is that today the cost of building materials is high enough, and every property owner is trying to maximize their purchases. Therefore, the information, how to calculate the floor area will not be excessive for the person who prefers to repair it personally.

Before you start work, you should determine the amount of activities, plan costs and calculate the number of building materials. For this, source data will be required. For this reason, it is important to know how to calculate the floor area indefinitely. This is especially true in places with uneven surfaces and non-standard layouts.

There are other reasons why floor surface size needs to be determined precisely:

Checking the quality of construction work;

This place needs to be redeveloped.

Definition of the area of ​​a rectangular area

Before calculating the floor area, it should measure the stocking calculator and tape measure. Rooms are usually in the form of a rectangle. To calculate their area, they use the formula known to everyone from the school: S \ u003d A x B, where A and B are the length and width. For example, at this point the dimensions are 3 and 4 meters, then the desired value will be 12 square meters. like this.

In this case when the room has a fireplace or built-in furniture items, you need to know their area and deduct from the total area. In the case of major floor repairs, most of the interior will have to be destroyed.

Wrong plan calculation of room square

It is more difficult to calculate a room with a polygon shape. Brick houses in layout often have triangular fossils and spherical elements in the photo.

In this case, before calculating the square of the floor, the room plan can be divided into separate zones. For example, if the room has an M-shaped layout, it should be divided into 2 rectangles, after which the area of ​​each should be calculated and the results obtained are folded.

Learning the area of ​​a triangular room

When the other part of the room is not perpendicular to the main area, it means that there is also a triangle between the two rectangles, with a right angle.

In this case, the triangle area is calculated by the formula: S \ u003d (A x B): 2 and add to the total result. For example, A \ u003d 2, B \ u003d 3, then S \ u003d (2x3): 2 \ u003d 3 m.

You can determine the area otherwise:

Calculate the square of the rectangle first.

Determine the area of ​​the beveled triangular angle.

From the square of the rectangle, the triangle area is truncated.

In this case when the triangle does not have a straight angle, Geo's formula S \ u003d p (P - A) (P - B) is used (P - C).

For example, its sides are equal to 5, 6 and 7 meters, then the calculations are done as follows:

Find the semi-version of triangle P \ u003d (5 + 6 + 7): 2 \ u003d 9.

In Geron's formula, the digital values ​​are transferred and the result is obtained: √ (9 x (9-7) x (9-6) x (9-5) (u003d 14.7 m².

Quadrature Room Room

Most often, in older building houses or on balconies there is a similar appearance that is attached to the room. First, 1/2 of the outer part of the circle is calculated and added to the rectangular area, formula S \ u003d r²: 2, in which:

R - The radius of the circle, built in squares.

For example, the room has a semicircular shaped balcony with a radius of 1.5 meters. By changing this number in the formula, we obtain the result: S \ u003d 3.14 x (1.5) ²: 2 u003d 3.5 m. Also read: "How to calculate the square meters of floor with different shapes of the room."

How to calculate the area of ​​the room

The order and floor for calculating the area of ​​the walls are different. The fact is that before calculating the square of the floor, you should find out the length and width of the room and calculate the walls it will be necessary to measure its height. So, first identify the perimeter in the room and multiply by the ceiling height.

For example, the floor dimensions are 3 and 4 meters, and the height of the room is 3 meters. In this case, the perimeter of the walls will be equal to (3 + 4) x2 00 u003d 14 m, and their area S \ u003d 14x3 u003d 42 m.

It should not forget about the squares of windows and doors. Their area is deducted after the wall count is completed. But on the other hand, they do not take into account and thus ensure some stock of materials.

Proportion between floor and windows

According to the snippet of 31-01-2003, Windows dimensions and their number depend on the floor quarters. Therefore, for residential apartment buildings, the ratio between window openings and floor surface areas will be 1: 5.5 to 1: 8. Like the upper floor, a minimum ratio of 1:10 is allowed there.

For private homes, this rate controls the 31-02-2001 snippet. According to this documentation, there should be at least one "square" source of natural light flux for every 8 "squares" of the floor surface. On the attic floor this ratio cannot be less than 1:10.

To ensure high quality repairs, you need to find out in advance how to calculate the floor area and other necessary rooms. The initial phase also provides for the acquisition of building materials and then costs will be reduced in the process of repairing, as they will not work in large balances and shipping costs will be incurred inefficiently.

A guide to calculating how to find the floor area will take longer than calculating an already existing building calculator, but it allows you to learn more accurate results.

What tools are used to calculate areas?

Using a 3D editor

On the computer, we set up editing programs, such as Arcade, AutoCAD, SketchUp.

Draw space in size, find data and mark the required pieces.

Advantage: Don't count yourself. It is advisable to use it to determine locations with irregular and complex geometry.

Failure: You have to spend some time studying programs. And without a computer or tablet, you can't do this.

We believe it is ourselves

Dimensions are listed, smartphone, drywall or wall. For calculations, we use a calculator, a table editor (Excel) or a column.

How to calculate square meters

Advantage: You can calculate directly on the object, set the required size. That’s enough to keep a pencil and a smart head.

Failure: Easy to make a mistake, skip the size, double count.

How to calculate the surface of the walls and floor in a rectangular room?

For example, consider the room in the figure below.

Dimensions are measured in meters.

Then give multiplication squares or linear counters.

To calculate the cost of labor, an accuracy of 1 cm is sufficient. (Up to two decimal marks). For example, the length of the room is 5.62 meters.

The information received is in the correct format. Which is more convenient than a sheet of paper which is a computer.

If we have information about the size, we calculate with your fingers, paper or Microsoft Excel.

The result of the calculation gives us the length of the walls in meters (in meters). Around the length of the perimeter of the bag in the room.
