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**) This is length of one side of the octagon - (
**h**) This is the height of the object

**Octagon Volume (V):** The calculator returns the volume (**V _{oct}**) 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`
