Answer: d) 168 in³
Explanation:
The volume of a right rectangular prism can be found by multiplying the base (the length times the width) by the height. Since we are given all the values needed, we can multiply them all together and find our answer.
V = length * width * height
V = 4 in * 6 in * 7 in
V = 168 in³
This gives us an answer of "d) 168 in³"
