The surface area of a rectangular prism can be calculated using the following formula:
Surface Area = 2lw + 2lh + 2wh
In this case, the base (l) is 15 inches, the height (h) is 12 inches, and the width (w) is 20 inches.
Surface Area = 2(15)(20) + 2(15)(12) + 2(20)(12)
Surface Area = 600 + 360 + 480
Surface Area = 1440 square inches
Therefore, the surface area of the rectangular prism is 1440 square inches.
base = 15 in x 20 in
height = 12 in
what is the surface area of the rectangular prism?
