    One thing that I should point out is that 3 cubic feet= \[1ft^{3}*\frac{12in}{1ft}\frac{12in}{1ft}\frac{12in}{1ft}=1728in\]

    What you need to do is realize that length*width*height=volume. So in this case, 24*18*something=1728. What does "something" have to be?

    Sorry, not 1728, 5184. 1 cubic foot is 1728 cubic inches, so 3 cubic feet is 5184 cubic inches.

    Just replace 1728 by 5184 and figure out what you need instead of 4.
