What is the surface area of the prism in square feet?
frutty [35]

The surface area of the rectangular prism is 52 square feet (ft^{2}), if the height is 4 feet, width is 3 feet and depth is 2 feet.

Step-by-step explanation:

          The given is,

                    A rectangular prism of

                     Let, h - height of the rectangular prism

                            w - Width of the rectangular prism

                            d - Depth of the rectangular prism

Step:1

        From given,

                     h = 4 feet

                     w = 3 feet

                     d = 2 feet

Step:2

        Formula to calculate the surface area of the rectangular prism is,

                      A = 2 (wd+hd+hw)

       Substitute the values of w,d and h

                           = 2 [(3×2) + (4×2) + (4×3)]

                           = 2 (6+8+12)

                           = 2 × 26

                           = 52

                       A = 52 Square feet

Result:

        Thus the surface area of the rectangular prism is 52 square feet (ft^{2}), if the height is 4 feet, width is 3 feet and depth is 2 feet.
