Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Ideal Euclidean geometry. Use one consistent length unit. Measurements and derived quantities use floating-point arithmetic. Apex lies directly above the center of a regular hexagon.
Example Calculation
- Hexagon base side: 2 units
- Perpendicular height: 3 units
Side 2 and height 3 give base area and volume both numerically 6√3; total area is 18√3.
Frequently asked questions
How do I use this calculator?
Enter hexagon base side, perpendicular height. The result updates automatically. Use Reset to restore the example values.
What method does it use?
apothem=√3 a/2; base area=3√3 a²/2; slant=√(h²+apothem²); V=base area × h/3; lateral area=3a × slant.. Ideal Euclidean geometry. Use one consistent length unit. Measurements and derived quantities use floating-point arithmetic. Apex lies directly above the center of a regular hexagon.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
