ELI5: Why do wasps build nests in hexagons if they do not store honey?
gpt
The honeycomb shape is designed to store eggs. After the queen lays her eggs, they're moved to the honeycomb where they're sealed inside the hexagons until they hatch.

Hexagons happen to be the most efficient for this task. It needs to be a tesselation, meaning you can put several of them next to each other un a repeating pattern without any overlap. The easiest options are triangles, squares, rectangles and hexagons. Hexagons use the least amount of wall material per area, so they're the easiest to build.
