Question

What is the surface area of a rectangular prism with a length of 14 feet, width of 7 feet, and height of 8 feet?​

Answer 1

A = 532 ft^2 total

Explanation:

There are 3 sets of 2 identical areas: 2 top/bottom, 2 sides, 2 ends.

Suppose the length is 14 ft, the width 7 ft and the height 8 ft.

A = 2 * (base area) + 2 * (end area) + 2 (side area)

= 2 * (98 ft^2) + 2 * (56 ft^2) + 2 (112 ft^2)

= 196 ft^2 + 112 ft^2 + 224 ft^2

A = 532 ft^2 total
