Answer:
The box has a total volume of 36 cubic inches.
Step-by-step explanation:
The total volume of the box is given by the volume that is filled with books plus the volume that doesn't have any books in it. Therefore, in order to solve this problem we must sum the two volumes. We have:
total volume = volume with books + volume without books
total volume = 24 + 12
total volume = 36 cubic inches
The box has a total volume of 36 cubic inches.
