| **The length of the box has the shape of a rectangular parallelepiped, the length is 30 cm and the width is 20 cm, which is equal to the height of the box if its volume is 7200 cm3.**

The volume of a parallelepiped is determined by the formula:

V = abH, where a – width, b – length, H – height.

H = V / ab.

Substitute numerical values into the formula and find the height of the box:

H = 7200 / (30 * 20) = 7200/600 = 12 (cm).

Answer: The height of the box is 12 cm.
