Length, width, height are parameters which characterize a parallelepiped. The parallelepiped represents a volume figure which sides are parallelograms. It is enough to know these parameters to calculate figure volume.

1. It is previously necessary to make the reservation. Length, width and height are parameters which are sufficient for calculation of volume only at a rectangular parallelepiped. The rectangular parallelepiped is meant as a figure at which all sides are formed by rectangles which form among themselves right angles. It means that in a rectangular parallelepiped the opposite sides are equal and parallel.
2. Now, having dealt with in what case it is possible to apply parallelepiped parameters as basic data, it is possible to start calculation of its volume. Volume is the measure characterizing quantity of the space occupied by an object. For calculation of volume of a parallelepiped it is necessary to multiply at each other all its parameters: length, width and height. A formula it can be expressed so: V = a*b*c where a, b and with are parameters.
3. For descriptive reasons it is possible to review an example: There is a rectangular parallelepiped which area of the basis is equal to 42 cm², and its height is 15 cm, it is required to find the volume of an initial figure. For the solution of a task it is necessary to notice that from all parameters only height is known. But the area of the basis which is multiplication at each other of length and width of a rectangle is given. From the formula stated above it is possible to draw a conclusion that the area of the basis is a*b of cm², then the volume of a rectangular parallelepiped will be so: 42*15 = 630 cm³Ответ: the volume of a figure will be 630 cm³
