What formulas does this calculator use?

Volume = hexagon base area × height; Surface area = 2 × hexagon base area + (perimeter × height) for the six rectangular side faces.

Where is this shape commonly used?

Hex nuts and bolt heads, pencils, and some architectural columns are common hexagonal prism examples.

Q: What is a hexagonal prism?

It's a 3D shape with two parallel hexagonal bases connected by six rectangular side faces — like a hexagonal pencil or nut/bolt head shape.

What Is a Hexagonal Prism Calculator?

A hexagonal prism has two regular hexagon ends connected by six rectangular sides — the shape of a pencil, a nut, or a honeycomb cell. This calculator finds the volume and total surface area from the hexagon's side length and the prism's height (length).

How to Use This Hexagonal Prism Calculator

Measure the side length of the hexagonal end.
Measure the height (length) of the prism.
Enter both values above and click Calculate to get the volume and surface area.

Formula

Hexagon Area = (3√3 / 2) × a²
Volume = Hexagon Area × H
Surface Area = 2 × Hexagon Area + (6a) × H

Worked Example

A hexagonal pencil has a side length of 4 mm and is 180 mm long. Hexagon Area = (3√3/2) × 4² ≈ 41.57 mm². Volume = 41.57 × 180 ≈ 7,483 mm³. Surface Area = 2(41.57) + (24)(180) ≈ 4,403 mm².
