The surface area of a rectangular prism with length l, width w, and height h is 2lw+2wh+2lh. Albert keeps his art supplies in a wooden box shaped like a rectangular prism. He wants to cover the box with silver glitter contact paper. The box has dimensions 12 inches by 10 inches by 6 inches. How many square inches of contact paper does Albert need to cover the box?

Albert need 504 square inches of contact paper

Step-by-step explanation:

l = 12 inches  ; w = 10 inches  ; h = 6 inches

Surface area = 2lw + 2wh +  2lh

                     = 2*12*10 +2*10*6 + 2*12*6

                     = 240 + 120 + 144

                     = 504 square inches
