Answer:
2 1/4 ft³ (Answer B)
Step-by-step explanation:
The length of the base is 3 units. The width of the base is also 3 units. The height of the solid is 1 unit.
Thus, the volume is V = (length)(width)(height) = (3 units)²(1 unit), or
9 units³.
Knowing that each cube has side 1/2, the actual volume is:
V = (3/2 ft)²( [1/2] ft) = 9/4 ft³ = 2 1/4 ft³ (Answer B)
