Construction

Ever wonder why bees use hexagons to make beehives? Two reasons. First, bees want to enclose the largest possible space with the least amount of wax. With this in mind, a circle would be best. So why don’t they use circular combs? Because hexagons are the shape with the most sides that “tesselate”. In other words, if you put a bunch of hexagons next to each other there will be no spaces between them. No shape with more than six sides will do this.
