Designing a box: an optimization problem

1. Different options for constructing a box
Brian is a stamp collector, and needs a box for the spare stamps he wants to trade.
He found a piece of square cardboard, 40x40 cm, and set about constructing from it a box in the following way:


He intends to cut out a square from each corner, then fold and tape the remaining shape to make the box.


To design the box, Brian must decide what size square to cut out from the corners of the cardboard.

Describe different options for designing the box

Make several proposals for constructing the box. For each proposal, record the dimensions of the box (the size of its base and height) and its volume.
  • Brian wants the box to have as big a volume as possible. Which of the plans you proposed is best suited for this purpose? Can you find an even better design?
