The width of the rectangular parallelepiped is 7.2 m, which is eight-ninths of its length, and the height

The width of the rectangular parallelepiped is 7.2 m, which is eight-ninths of its length, and the height is 2.5 m. find its volume.

Let us determine the length of a rectangular parallelepiped, provided that its width, equal to 7.2 m, is 8/9 of it.
In order to find out the value of an integer, if its part is known, it is necessary to multiply it by the denominator of the fraction and divide by the numerator:

7.2 * 9: 8 = 8.1 m.

According to the terms of the assignment, the height of such a figure = 2.5 m.
The volume of such a figure is calculated by the formula:

V = a * b * c = 8.1 * 7.2 * 2.5 = 145.8 m³.
