Answer:

D) 180 square feet

Step-by-step explanation:

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

SA = 2(ab) + 2(ac) + 2(bc), where 'a', 'b' and 'c' are the side lengths of the prism

Given 3 feet by 6 feet by 8 feet:

a = 3

b = 6

c = 8

SA = 2(3*6) + 2(3*8) + 2(6*8) = 36 + 48 + 96 = 180 square feet
