Enter a value for all fields

This **Volume of a Decagon** formula,(**V _{decagon}=^{5}/_{2 }• √(5+2√5) • s^{2}• h**) computes the volume a column with a regular decagon face, a polygon with 10 equal sides of length (

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

- (
**s**) - Length of the sides of the decagon - (
**h**) - Height of the decagon column

**Decagon Volume (V):** The volume is returned in cubic meters. However, the volume can be automatically converted into many other cubic units via the pull-down menu.
