Answer 1

• B. 8.76 square feet

Each triangle face has height of 7 ft and base of 0.6 ft and the base of the pyramid is the square with side of 0.6 ft.

Total surface area includes a square base and four triangular faces and the measure of it is:

• S = 0.6² + 4*(1/2)*0.6*7 = 0.36 + 8.4 = 8.76 ft²

The matching choice is B.
