Enter a value for all fields

The **Octagon Volume** calculator computes the volume (**V**) of an octagonal shaped column or structure * Regular Octagon* based on the length of its sides (**s**) and height (**h**)

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

- (
**s**) Length of one side of the octagon - (
**h**) Height of the object

**Octagon Volume (V):** The calculator returns the volume in cubic yards. However, this can be automatically converted to other volume units (e.g. gallons, cubic inches) via the pull-down menu.

A regular octagon is an eight sided polygon where all of the sides are the same length (**s**), with a height (**h**), one can create a octagon shaped object (e.g. column or planter)

Volume of a uniformed shaped object such as an octagon column is derived by the following formula:

Where the Area =`2(1 + sqrt(2))*s^2` for an octagon. Therefore, the volume of an octagon column can be computed with the following formula:

`V_(oct)= 2 (1 + sqrt(2)) * s^2 * h`

**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.
