Pick one

Official solution

The volume of a rectangular box equals the area of its base times its height.

Thus, the height equals the volume divided by the area of the base.

The area of the base of the given box is $\text{2 5 =10 cm 2}$ .

Therefore, the height of the given box is $\text{30 10 = 3 cm}$ .
