This **Volume of a Pentagon** calculator computes the volume of a regular pentagon shaped objects with 5 equal sides of length (**s**) and a height (**h**).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**s**) - Length of the sides of the pentagon - (
**h**) - Height of the pentagon shaped object.

**Volume of a Pentagon (V):** The volume is returned in cubic meters. However, this can be automatically converted to other volume units (e.g. gallons, cubic feet) via the pull-down menu.

The formula for the volume of a pentagon is:

V =¼•√(5+2•√5)•s^{2}•h

where:

- V = Volume of Pentagon
- s = Side Length
- h = Height

A regular pentagon has five equal sides and equal angles. * The U.S. Pentagon * A pentagon volume is a pentagon shaped object with a regular pentagon cross-section (area) and perpendicular height.

One famous pentagon shaped object is the U.S. Pentagon, home of the U.S. military. The Pentagon has side lengths (**s**) of 921 feet, and a height (**h**) of 77 feet. Use the calculator and compute the volume.
