The length of the rectangular parallelepiped is 45 cm, the width is 4/9 of the length and 12/7

The length of the rectangular parallelepiped is 45 cm, the width is 4/9 of the length and 12/7 of the height. Find the volume?

By the condition of the problem, the length of the rectangular parallelepiped is 45 cm, and the width is 4/9 of the length. Find the width of the rectangular parallelepiped:

1) 45 * 4: 9 = 20 (cm).

The height is 12/7 of the width. Find the height of the rectangular parallelepiped:

2) 20 * 12: 7 = 34 (approx) cm.

Let’s calculate the volume of a rectangular parallelepiped equal to the product of its three dimensions:

3) V = 45 * 20 * 34 = 30600 (cm³).

Answer: the volume of a rectangular parallelepiped is 30600 cm³.
