Hey! Glad you enjoyed my ramblings. I used to be in IB myself.

To elaborate upon the inefficiencies of packing circular waffles into square boxes, you could write some sort of function calculating the amount of empty space, given some waffle radius and box height, width, and depth. Then take the derivative, optimize, and voila! Solved for the maximum packing density of waffles and invented the new Mhatre Theorem. Enjoy your IA!
