Answer:
B. 42 cubic units
Explanation:
The formula for volume of a rectangular prism is given by :
V = lwh, where
- V is the volume in cubic units,
- l is the length,
- w is the width,
- and h is the height.
In the diagram, the length is 8 units, the width is 1 1/2 units (i.e., 1.5 units), and the height is 3 1/12 units (i.e., 3.5 units).
Thus, we plug in 8 for l, 1.5 for w, and 3.5 for h in the volume formula to find V, the volume in cubic units:
V = (8)(1.5)(3.5)
V = 12(3.5)
V = 42
Thus, the volume of the prism is 42 cubic units (answer choice B.)
