1.) What is the surface area of the figure below?

Step-by-step explanation:

length (l) = 3 ft

Width (w) = 3 ft

Height (w) = 6 ft

Surface area = 2*( lw  + wh + hl)

                    = 2* (3*3 + 3*6 + 6*3)

                    = 2*(9 + 18 + 18)

                   = 2 *  45

                   = 90 square ft

the answer will be the last one
