What is the surface area of the rectangular prism below 7, 7, 14

Surface Area   A = 490 cm²

Step-by-step explanation:

Surface area of a prism A = 2(w l +h l + h w)

where l = length

        w = width

        h = height

l = 7 cm; w = 7 cm ; h = 14 cm

Surface Area = 2 { ( 7 × 7) + ( 14 × 7) + ( 14 × 7)}

            A = 2 { 49 + 98 + 98}

            A = 2 × 245

            A = 490 cm²
