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.
