The length of the rectangle of the parallelepiped is 50cm, the width is 80% of the length

The length of the rectangle of the parallelepiped is 50cm, the width is 80% of the length, and the height is -2/5 of the length. Find the volume of this parallelepiped.

Let’s write down the given parameters of the parallelepiped. The length is 50 cm; width = 0.8 * (width) = 0.8 * 59 cm = 40 cm. Height is 2/5 * length = (2/5) * 50 cm = 20 cm.

The volume of a parallelepiped is equal to the product of its three dimensions, expressed in one common dimension, in our case it is in centimeters.

Volume v = length * width * height = 50 cm * 40 cm * 20 cm = 40,000 cm ^ 3 = 40,000 m ^ 3/100 ^ 3 = 0.04 m ^ 3.

Answer: v = 40,000 m ^ 3.
