Answer:
18750 inches cubed
Step-by-step explanation:
(note that this is not a cube if the base is 750 and the height is 25; it would be a rectangular prism)
The volume of a rectangular prism is Bh, where B is the base area and h is the height. In this case, B = 750 and h = 25. So, we plug these into the equation:
V = Bh
V = 750 * 25 = 18750
Thus, the answer is 18750 inches cubed.
Hope this helps!
