The height of the rectangle is 25 m, the width is 20% of the height and the length is 4/5 of the height. find the volume.

First, let’s find the width if, according to the problem statement, it is known that it is 20% of the height:

25 m – 100%,

x m – 20%.

x = 20 * 25/100

x = 5

Now you can find the length if, according to the data in the problem, it is known that it is 4/5 of the height:

25 * 4/5 = 20

It remains to determine the volume if all 3 measurements are known:

V = a * b * h, where a – length, b – width, h – height.

V = 20 * 5 * 25 = 2500 m3.

Answer: the volume is 2500 m3.
