In your answer, specify whether he should use total surface area or lateral surface area. Calculate the one you choose, give that measurement of the box, and then explain how you calculated it.

Answer 1

Answer:

Surface Area = 2lw + 2lh + 2hw  =  2(lw+lh + hw) = 2(12x8 + 12x4 + 4x8)  = 2(96+48+32) = 2(176) = 352 square inches

Step-by-step explanation:

Answer 2

Answer:surface area = 2lw + 2lh + 2hw  =  2(lw+lh + hw) = 2(12x8 + 12x4 + 4x8)  = 2(96+48+32) = 2(176) = 352 square inches
