July 25, 2021 | education

| V = abc, where a is the length, b is the length and c is the height of the rectangular parallelepiped.

a = 21 cm.

The width is 3/7 of the length, which means:

b = 21 * 3/7 = 9 (see)

The width is 30% of the height, which means:

c = 9: 30 * 100 = 0.3 * 100 = 30 (see)

V = abc = 21 cm * 9 cm * 30 cm = 5670 cm cubed.

Answer: 5670 cm cubed.
