Question

HELPPP
Find the total surface area of a rectangular prism with dimensions of 8 ft x 4 ft x 3 ft. Select the correct answer.

Answer 1

Formula: A = 2wl + 2lh + 2hw

So... : A = 2(4x8) + 2(8x3) + 2(3x4)

         A = 2(32)   + 2(24)   + 2(12)

         A = 64 + 48 + 24

Answer: A = 136 (add them all up)

Hope this helps!!!
