How to calculate the volume of the room

Volume — a quantitative characteristic of the space. The amount of space is determined by its shape and linear dimensions. The volume is closely related to the concept of capacity, i.e. the volume of the internal space of the vessel, packing box, etc. the Accepted units of measure — measurements SITMA C and derivatives from it — cubic meter m3, cubic centimeter, liter.

You will need

• To measure the amount of space you will need a tape measure, sheet of paper, calculator, pen.

Instruction

1. Each room, for example room represents, from a geometrical point of view a rectangular parallelepiped. A parallelepiped is a three - dimensional figure whose six faces (for example-room: 4 walls, ceiling, floor), and each of them is a rectangle. The formula for finding the volume of a rectangular parallelepiped: V=abc. The volume of a rectangular parallelepiped equals the product of its three dimensions. In addition to this formula it is possible to measure the volume of the room by multiplying the area of the floor to a height.
2. Now proceed to the calculation of the volume of the room. Measure the length of one wall (long wall),then measure the length of the second wall (short wall). The measurements were performed on the floor at skirting.Tapes hold it steady. Now measure the height of the room, to do this go to one of its corners, and precisely measure the height of the corner from floor to ceiling. The received data write down on a piece of paper not to forget. Now move on to compute: multiply the length of the long wall to the short wall length, the obtained result (number)multiply by the height and you will get the desired result. The volume of the premises calculated in different cases: 1) in case of purchase of air conditioner, because air conditioners are designed for a certain amount of space; 2) the installation of radiators in the rooms, as the number of sections in the radiator depends on the volume of the room.
3. If you have a room of irregular shape, that is, consists of like a big box and small. In this case, it is necessary to measure the volume of each of them separately and then folded. If your room has an alcove (a niche with a semicircular shape), then its volume needs to be calculated by the following formula volume of a cylinder. The volume of any cylinder is equal to the product of the area of the base to the height: V=π r2 h, where π is the number PI = 3.14, r2 is the square of the radius of the cylinder, h is the height. Imagine your alcove as part of a cylinder, calculate the volume as if the whole cylinder, then see what part of this cylinder is your alcove,subtract from the total amount of the excess.
