Equations
- The area of a regular hexagon with side length l is equal to six times the area of an equilateral triangle with side length l, i.e.:
3√3∕2 · l2
- Because the diameter of a hexagon is twice its side length, the area of a hexagon with diameter l is a quarter of this, i.e.:
3√3∕8 · l2
Dissection
The hexagon of side 1 may be dissected into:

- Octahedral truncate (8×, 57%)
- Tetrahedral truncate (4×, 50%)
- Hexagonal prism (2×, 25%)
