This Volume of a Heptagon calculator computes the volume of a regular heptagon shaped objects with 7 equal sides of length and a height. 
INSTRUCTIONS: Choose units and enter the following:
- (s) Length of Sides
- (h) Height of Column
Volume of a Heptagon (V): The calculator returns the volume in cubic meters and the surface area of the heptagon column in square meters. However, these can be automatically converted to compatible units via the pull-down menu.
The Math / Science
A regular heptagon has seven equal sides and equal angles. A heptagon volume is a heptagon shaped object with a regular heptagon cross-section (area) and perpendicular height.
The formula for a heptagon column (volume) is:
`V = 7/4 * cot(pi/7) * s^2* h`
where:
- V = Volume of Heptagon Column
- s = Side Length of Heptagon Base and Top
- h = Height of the Column
Heptagon volumes appear in man-made objects. For the Area of a Heptagon shaped surface, CLICK HERE.
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.
