The width of the rectangular parallelepiped is 7.2 cm, which is 3/4 of the length and 5/4 of the height. Find the volume of this parallelepiped.

1. According to the problem statement, a rectangular parallelepiped is given.

Its width is 7.2 cm.

It is known that the width of the figure is 3/4 of the length.

Find the length of the rectangular parallelepiped.

7.2 / 3 * 4 = 2.4 * 4 = 9.6 cm.

2. The problem says that the width is 5/4 of the height.

Let’s calculate the height of the figure.

7.2 / 5 * 4 = 1.44 * 4 = 5.76 cm.

3. Knowing all the parameters, you can find the volume of the rectangular parallelepiped.

7.2 * 9.6 * 5.76 = 69.12 * 5.76 = 398.1312 cm3.

According to the condition of the problem, the volume value should be rounded to the nearest whole.

So it is equal to 398 cm3.

Answer: The volume will be 398 cm3.
