Question

PLEASE HELP!! Find the surface area of each figure to the nearest tenth. Show your work.

Answer 1

Surface area = 2(ab+bc+ac)
a=5.2 ft,  b=2.4 ft, c=3.5ft

Surface area = 2(5.2 * 2.4 + 2.4 * 3.5 + 3.5 * 5.2) =
                         2(12.48 + 8.4 + 18.2) = 
                         2 * 39.08 =
                         78.16 ≈ 78.2 ft²   ← to the nearest tenth
