Start with a $10$ by $10$ grid.

If you cut out each corner square, it could be folded into an open-top box that had an $8$ by $8$ base and was $1$ square deep. That means that the box would be able to hold $64$ cubes.

What size square should you cut out of each corner to make the box that would hold the greatest number of unit cubes?
