    The surface area of a prism = 2 × area of base + perimeter of base × H

    92 ft^2 is my answer 12 ft^2 is my base area 16 is my perimeter * height (5) = 80 80 + 12 = 92 ft^2

    Surface Area: rectangular base 2 ft by 6 ft, height 5 ft Sa = 2tops + 2lefts + 2fronts .... Sa = 2(6*2) + 2(6*5) + 2(5*2) Sa = 24 +60 +20 Sa = 60 + 44 = 104, right?

    I found the base area... then the perimeter * by height then added my base area to the lateral area

    surface area of a box is just adding up all the faces... each face consists of 2 parts to compute area

    2(6.2) + 2(6.5) + 2(5.2) is the total of all faces
