Answer:
The correct answer is option D. 126 in³
Step-by-step explanation:
<u>Formula:-</u>
Volume of cuboid - lbh
l - Length of cuboid
b - Breadth of cuboid
h - Height of cuboid
<u>To find the volume of prism</u>
Here rectangular prism is like a cuboid.
l = 8 in, b = 4 1/2 = 9/2 and h = 3 1/2 = 7/2
Volume = lbh
= 8 * 9/2 * 7/2 = 126 in³
Therefore the correct answer is option D. 126 in³
