this whole thing makes no sense to me. can you please answer it?
The major part of this problem involves volume.
The volume of a rectangular prism is:
V = l * w * h
Since the bottom layer is 2 inches deep --
V = 24 * 14 * 2
V = 672 cubic inches
Now figure out the volume of each of the other two layers.
