Answer:
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
190.
