A box held 387.45 cubic inches of space inside. If the length was 6.3 inches and the width measured 8.2 inches, find the box’s height.

The correct answer is: 7.5 inches

Given ,Volume of box = 387.45 cubic inches  ,length of box = 6.3 inches , width of box = 8.2 inches
Let h be the height of the box.
Volume = 6.3 × 8.2 × h
6.3 × 8.2 × h = 387.45
h = 7.5 inches
Therefore, height of the box is 7.5 inches.
