Periodically, we need to know the area and the volume of the room. These data may be needed when designing heating and ventilation, when purchasing building materials and in many other situations. Also periodically need to know the walls of the walls. All this data is calculated easily, but will pre-work a roulette - measure all the required dimensions. On how to calculate the area of the room and the walls, the size of the room and will be discussed further.
Often it is necessary to calculate the sidelines of the room, its volume
Room Square in Square meters
It is easy to consider, it is only required to recall the simplest formulas as well as to carry out measurements. For this we will need:- Roulette. Better - with the retainer, but the usual one will fit.
- Paper and pencil or pen.
- Calculator (or count in a column or in mind).
The set of tools is simple, there is in every farm. It is easier to measure with an assistant, but you can cope with yourself.
First you need to measure the length of the walls. It is advisable to do it along the walls, but if all of them are forced heavy furniture, you can carry out measurements and in the middle. Only in this case, follow the roulette tape lying along the walls, and not the defective - the measurement error will be less.
Rectangular room
If the room is the right form, without protruding parts, calculate the room area simply. Measure the length and width, write on a piece of paper. Write numbers in meters, after the comma put centimeters. For example, the length is 4.35 m (430 cm), the width is 3.25 m (325 cm).
How to calculate the square
Found numbers in short, we get the room in square meters. If we turn to our example, then the following will be: 4.35 m * 3.25 m = 14,1375 square meters. m. In this magnitude, usually two digits after the semicolon are left, it means somewhat. Total, the calculated square of the room is 14.14 square meters.

Placement of irregular shape
If you need to calculate the area of the wrong shape, it is broken into simple figures - squares, rectangles, triangles. Then they measure all the necessary dimensions, produce calculations according to the well-known formulas (there is a little lower in the table).
Before calculating the room area, also carry out changes. Only in this case, the numbers will not be two, and four: the length and the width of the protrusion will be added. The dimensions of both pieces are considered separately.
One example is in the photo. Since both are a rectangle, the area is considered in the same formula: the length is multiplied by the width. The number found should be taken or add to the room size - depending on the configuration.
Square Square
Let us show on this example how to calculate the room with a protrusion (depicted in the photo above):
- We consider the square without protrusion: 3.6 m * 8.5 m = 30.6 square meters. m.
- We consider the dimensions of the serving part: 3.25 m * 0.8 m = 2.6 square meters. m.
- We fold two quantities: 30.6 square meters. m. + 2.6 square meters. m. = 33.2 kV. m.
There are also rooms with beveled walls. In this case, we divide it so that rectangles and triangle are obtained (as in the figure below). As you can see, for a given case, you need to have five sizes. It was possible to smash differently, putting a vertical, not a horizontal line. It does not matter. A set of simple figures is simply required, and the method of their allocation is arbitrary.
How to Calculate Room Square Wrong Shape
In this case, the order of calculations is:
- We consider a large rectangular part: 6.4 m * 1.4 m = 8.96 square meters. m. If rounded, we get 9, 0 sq.m.
- Consider a small rectangle: 2.7 m * 1.9 m = 5.13 kV. m. Rounded, we get 5.1 square meters. m.
- We consider the area of the triangle. Since it is with a straight angle, it is equal to half of the area of the rectangle with the same dimensions. (1.3 m * 1.9 m) / 2 = 1.235 square meters. m. After rounding, we get 1.2 square meters. m.
- Now we are all fold to find the total area of the room: 9.0 + 5,1 + 1.2 = 15.3 square meters. m.

The layout of the premises can be very diverse, but the general principle you understood: we divide on simple figures, we measure all the required dimensions, calculate the square of each fragment, then we add everything.
Formulas for calculating the area and perimeter of simple geometric shapes
Another important note: the room, floor and ceiling area are all the same values. Differences may be if there are some semi-colones that do not reach the ceiling. Then the quadrature of these elements is deducted from the total quadrature. As a result, we get the floor area.
How to calculate the square of the walls
The determination of the walls of the walls is often required when purchasing finishing materials - wallpaper, plaster, etc. For this calculation, additional measurements are needed. The width and length of the room will be needed:
- ceiling height;
- Height and width of doorways;
- Height and width of window openings.
All measurements - in meters, as the square of the walls are also taken to measure in square meters.
The most convenient dimensions are applied to the plan.
Since the walls are rectangular, then the area is considered for a rectangle: a length is multiplied by the width. In the same way, we calculate the size of the windows and doorways, their dimensions are subtracted. For example, calculate the area of the walls shown in the diagram above.
- Wall with door:
- 2.5 m * 5.6 m = 14 kV. m. - Total area of the long wall
- How much does the doorway take: 2.1 m * 0.9 m = 1.89 sq.m.
- Wall without taking into account the doorway - 14 sq.m - 1.89 square meters. m = 12,11 square meters. M.
- Wall with window:
- Quadrature of small walls: 2.5 m * 3.2 m = 8 sq.m.
- How much it takes the window: 1.3 m * 1.42 m = 1.846 kV. m, round, we get 1.75 sq.m.
- Wall without window opening: 8 square meters. M - 1.75 sq. M = 6.25 sq.m.
Find the total area of the walls will not be difficult. We fold all four digits: 14 sq.m + 12.11 sq.m. + 8 sq.m + 6.25 sq.m. = 40.36 square meters. m.

Room volume
Formula for calculating room volume
For some calculations, the size of the room is required. In this case, three values are multiplied: width, length and room height. This value is measured in cubic meters (cubic meters), called more cubature. For example, use the data from the previous paragraph:
- Long - 5.6 m;
- width - 3.2 m;
- Height - 2.5 m.
If you multiply, we get: 5.6 m * 3.2 m * 2.5 m = 44.8 m3. So, the size of the room is 44.8 cube.
