The width of a rectangular parallelepiped is 7.2 cm, which is 0.8 of its length and 0.18 of its height.

The width of a rectangular parallelepiped is 7.2 cm, which is 0.8 of its length and 0.18 of its height. calculate the volume of the parallelepiped .

The first step is to calculate what the length of the rectangular parallelepiped is, knowing that 0.8 part of it is 7.2 cm. To find a number by its part, you need a number that expresses this fraction divided by a part.

7.2 / 0.8 = 9 cm.

Let’s calculate what the height is.

7.2 / 0.18 = 40 cm.

Let’s calculate what the volume of the parallelepiped is. To do this, we multiply all three values – length, width, height.

V = 7.2 * 9 * 40 = 2 592 cm³.

Answer: 2592 cm³.
