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
