Answer:

135 ft²

Step-by-step explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 2.5 ft.

           h = 6 ft.

          s1 = 6.5 ft.

          s2 = 6 ft.

         s3 = 2.5 ft.

          L = 8 ft.

plugin values into the formula:

A = 2.5*6 + 8(6.5 + 6 + 2.5)

   = 15 + 8(15)

   = 135 ft²
