The length of the rectangular parallelepiped is 40cm. Its width is 1/2 of the length and 20%

The length of the rectangular parallelepiped is 40cm. Its width is 1/2 of the length and 20% of the height. Calculate the volume of the parallelepiped.

First, let’s draw a rectangular parallelepiped.

Then we denote the length as 40 cm, since its width is 1/2 of the length, then the length is 20 cm.

Since the width is 20% of the height, the height is: 20 / 0.2 = 100 cm.

While the volume is equal to the product of length and width and height, then the volume is: 100 * 20 * 40 = 80,000 cm3.
