Question

A rectangular prism is 3 feet long, 4 feet wide, and 4 feet high. What is it's surface area?

Answer 1

80 ft

Explanation:

The formula for finding the surface area of a rectangular prism is:

A = 2(wl + hl + hw)

A = 2({4x3} + {4x3} + {4x4})

A = 2 (12 + 12 + 16)

A= 2 ( 40)

A = 80 feet
