Question

Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.

the length is 3 yd, the base is 7 yd, and the width is 6 yd

Answer 1

The surface area is 162 yards

Explanation:

A = 2(w l + h l + h w)

A = 2(7 (3) + 6 (3) + 6 (7))

7 x 3 = 21

6 x 3 = 18

6 x 7 = 42

21 + 18 +42 = 81

81 x 2 = 162
