Answer:
It would be 925 inches cubed.
Explanation:
To find the volume, know that to find the volume of any rectangular prism (which is what this is) is to do Length * Width * Height to get the volume.
By doing, 18.5 * 12.5 * 4, you'll get your answer.
18.5 * 12.5 * 4 ---> 925
Remember to make in the unit of inches (because that's the unit it was asked in) and to write cubed at the end (since you are finding the area of a 3d object).
