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=6 ft,  b=12 ft, c=4.5 ft

Surface area = 2(6 * 12 + 12 * 4.5 + 4.5 * 6) =
                         2(72 + 54 + 27) = 
                         2 * 153 =
                         306 ft²
