This question of why bees use hexagons instead of other shapes, caught the attention of a Roman scholar over 2000 years ago, in 36BC. The scholar, whose name was Marcus Terentius Varro, proposed that hexagons hold more honey than other shapes because they break up flat space into little units more economically, using less wax whilst doing so. In other words, hexagon honeycombs hold the most amount of honey while using the least amount of wax.
