This practical challenge invites you to investigate the different

This activity investigates how you might make squares and pentominoes from Polydron.
If you had 36 cubes, what different cuboids could you make?
There is just a need to be systematic here. Try taking the
information in a different order, starting with facts that have the

plates with M only has two possible outcomes.
