Answer:
D. 108.25 sq in
Step-by-step explanation:
Area of triangle = bh/2
Area of bottom triangle = 4.3(5)/2 = 10.75
Area of a lateral triangle = 13(5)/2 = 32.5
Area of 3 lateral triangles = 3(32.5) = 97.5
Total surface area = 10.75 + 97.5 = 108.25
Volume = Length x Length x Length
Volume = Length³
Length = ∛Volume
Given that Volume = 756 in³
Length = ∛756
Answer: ∛756 (option A)
