A wedge of cheese in the shape of a triangular prism is shown below.
Find the surface area of the cheese.

Type your result in the empty box provided below.
_square feet.

144 ft^2

Step-by-step 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

it is 10.6 according to my calculations
