What is the surface area of this design?

Option D:

The surface area of the design is 197 in².

Solution:

Area of the front face =

                                      = 35 in²

Area of back face =

                                      = 35 in²

Area of left side face = base × height

                                     = 5 × 5

                                     = 25 in²

Area of top face = base × height

                            = 5 × 5

                            = 25 in²

Area of bottom face = base × height

                            = 9 × 5

                            = 45 in²

Area of right side face = base × height

                            = 5 × 6.4

                            = 32 in²

Surface area of the design = 35 + 35 + 25 + 25 + 45 + 32

                                             = 197 in²

The surface area of the design is 197 in².

Option D is the correct answer.

expression #3 is not equivalent. the others are.
