Answer :
The volume of the composite solid is calculated as approximately: 112.57 in³ (option A).
How to find the volume?
The volume of the composite solid = volume of square prism + volume of cylinder.
Volume of square prism (V) = a²h, where:
Base edge = 5 in.
height (h) = 4 in.
Volume of square prism (V) = 5² * 4
V = 100 in.³
Volume of cylinder (V) = πr²h, where:
r is the radius = 2 in.
h is the height = 1 in.
Volume of cylinder (V) = π * 2² * 1 ≈ 12.57 in.³
Volume of the composite solid = 100 + 12.57
V = 112.57 in³ (option A).
