    Answer: The surface area is 142m^2

    Step-by-step explanation:

    -The formula:

    A = 2(wl+hl+hw)

    -Solve:

    A = 2 (5 × 7[tex])[/tex] +2 (3 × 7) + 2 (3 × 5)

    A = 10 × 7 + 6 × 7 + 6 × 5

    A = 70 + 6 × 7 +6 × 5

    A = 70 + 42 +6 × 5

    A = 112 + 6 × 5

    A = 112 +30

    A = 142

    Therefore, the surface area of a rectangular prism is 142 m ^2.
