The document discusses an optimization problem involving bees choosing the shape of their cells. Bees choose a hexagonal shape for their cells in order to save wax by using the least amount of building material needed to construct their cells. The hexagonal shape allows bees to construct cells with the maximum storage capacity using the minimum amount of wax.
