Answer:
158 square feet
Step-by-step explanation:
The surface area of a prism is found using the following formula: SA = 2(lh+lb+bh). This formula takes the area of each face (6 in total( and adds them together to find a total sum. Substitute l = 8, b = 3 and h = 5 to solve for the surface area.
SA = 2(lh+lb+bh)
SA = 2(8*5+8*3+3*5)
SA = 2(40 + 24 + 15)
SA = 2(79)
SA = 158
