What is a simple way to solve this problem? I can do this problem by drawing the large block and trying small blocks, but very time consuming. I assume there must be a wise way to try the small blocks.
What is the maximum number of rectangular blocks with dimensions 3 inches by 5 inches by 2 inches that will fit into a box 15 inches by 30 inches by 12 inches?
Compute the volume of the large and small blocks. The dimensions have been chosen so you can show you can pack them perfectly, so just divide the volumes.
