Find the volume of a rectangular parallelepiped whose width is 63 cm, the length is 3/7 of the width

Find the volume of a rectangular parallelepiped whose width is 63 cm, the length is 3/7 of the width, and the height is 5/3 of the length.

In order to find the volume of a rectangular parallelepiped, you need to know the lengths of all its sides.

We calculate the length, which is 3/7 of the width, equal to 63 cm.To do this, divide the integer by the denominator of the fraction and multiply by the numerator:

63: 7 * 3 = 9 * 3 = 27 cm.

The height is 5/3 of the length:

27: 3 * 5 = 9 * 5 = 45 cm.

V = a * b * c = 63 * 27 * 45 = 76545 cm³.
