When bees make hexagons in their hives, the six-sided shapes fit together perfectly. In fact, we’ve actually never seen bees make any other shape. Hexagons are useful shapes. They can hold the queen bee’s eggs and store the pollen and honey that the worker bees bring to the hive.
When you think about it, making circles wouldn’t work too well. It would leave gaps in the honeycomb. The worker bees could use triangles or squares for storage. Those wouldn’t leave gaps. But the hexagon is the strongest, most useful shape. The geometry of this shape uses the least amount of material and holds the greatest volume.
Hexagons are often found in the design world in practical situations, like bridges, airplanes, and cars. They give materials extra strength and minimum weight.
After all, materials made with hexagon shapes can handle a lot of force, even if they are made out of lighter weight materials.
