| **The height of the rectangular parallelepiped is 7/9 m, and its length is 4 whole 2/9 m more. Find the volume of a parallelepiped if it is known that its width is 3 whole 5/7 m less than its length.**

Let’s find the length of the parallelepiped:

7/9 + 4 2/9 = 4 9/9 = 5 m;

Let’s find the width of the parallelepiped:

5 – 3 5/7 = 4 7/7 – 3 5/7 = 1 2/7 m;

To find the volume of a parallelepiped, you need to multiply the height, length and width:

V = a * b * c = 5 * 1 2/7 * 7/9 = 5/1 * 9/7 * 7/9 = 5/1 = 5 m ^ 3.

Answer: 5 m ^ 3.
