A box is 5 inches high, 10 inches wide, and 8 inches deep. What is the volume of the box?

A 400 cubic inches.

explanation

To calculate the volume of a box, we multiply its height, width, and depth. Given the dimensions of the box:
Height = 5 inches
Width = 10 inches
Depth = 8 inches

The volume (V) of the box is calculated as follows:
V = Height x Width x Depth
= 5 inches x 10 inches x 8 inches
= 400 cubic inches

Therefore, the volume of the box is 400 cubic inches.
