Why Do Bees Build Hexagonal Cells?

Have you ever wondered why bees build hexagon-shaped cells?

Isn't it fascinating? Why hexagon? Why not other shapes? And these apparently simple, instinct-driven creatures could build the perfect-six-sided-hexagon which, when you stack them up together, form a perfect array of honeycomb.

More than 2000 years ago, Marcus Terentius Varro proposed an answer to this question. He thought maybe honeycomb built of hexagons can hold more honey and require less building wax, and this answer has since been called "The Honeybee Conjecture".
