The Book Box
Understand the puzzle
The exact puzzle
Book boxes each measure 4 units long, 3 units wide, and 2 units tall. The shipping crate is a cube, 5 units on every side. Boxes must sit straight (no tilting), but you may turn any box any way you like. What is the largest number of book boxes that can fit in the crate?
