Volume is the space occupied by a body. It is simple to calculate the volume of the correct subject at which it is possible to determine easily parameters (length, width, height). It is necessary to multiply the found sizes only. It is much more difficult to determine volume at any figure.
Instruction
1. The way of measurement of volume of a subject by means of water was dug out by the Greek scientist Archimedes. For scoping of any body it is necessary to take the container with liquid, it is better if capacity is transparent. It is necessary to apply a scale of division on a vessel and to measure the volume occupied by water. After that it is necessary to ship a body which volume you want to learn in water. As soon as water rises, you need to note new level. The difference will also be equal in the levels received as a result of measurements to the volume of the shipped body.
2. Besides, it is possible to determine subject volume by measurement of amount of the water which is forced out by it. For this purpose it is necessary to ship a body in the vessel up to the top filled with water. At the same time the water which is forced out by it needs to be poured in other capacity and to measure the volume which will equal to the required volume of a body.
3. When finding volume of a hollow body it is also possible to use water. For this purpose it is necessary to fill with it the available subject, and then to pour water in a glass on which the division scale is applied. The measured volume of a body will be equal to the volume of the water contained in it.
4. It is possible to calculate the volume of any body, knowing its density and weight. For this purpose it is necessary to divide the mass of the available subject into its density. It is possible to learn density of substance of which any given subject is made of the help tables "Density of Solid Bodies".
5. For calculation of some figures mathematical formulas are removed. So, for example, for finding of volume of a cylinder it is necessary to know its radius and height. You receive cylinder volume by the work of number of Pi on a square of radius and height of a body (V=π*R2*H).
