This Volume of a Dodecagon formula, (V=3(2+√3)•s2•h), computes the volume a column with a regular dodecagon face, a polygon with 12 equal sides of length (s) and a height (h). 
Regular Dodecagon Column
INSTRUCTION: Choose units and enter the following:
- (s) - Length of the sides of the dodecagon
- h - Height of the dodecagon column
Volume of a Dodecagon (V): The volume is returned in cubic meters. However, the volume can be automatically converted to other volume units like gallons or cubic miles via the pull-down menu.

The Math / Science
A regular dodecagon has twelve equal sides and equal angles.
Volume is a three dimensional measurement of the amount of space taken up by an object. 
Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluids have separate volume units such as liters, fluid ounces, cups, gallons, and barrel.
The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.
In many cases, the calculators are for a column with a geometric shaped base and vertical sides. One basic formula for volume is area times a Height when the volume has vertical sides.
