​Type your result in the empty box provided below.
_______square feet.

Answer 1

144 ft^2

Explanation:

Back (vertical): (4 ft)(8 ft) = 32 ft^2

Right side (vert.): (4 ft)(6 ft) = 24 ft^2

Front (vert.): (4 ft)(10 ft) = 40 ft^2

Top (horizontal): A = (1/2)(6 ft)(8 ft) = 48 ft^2 total (top and bottom)

Total surface area is (32 + 24 + 40 + 48) ft^2, or 144 ft^2
