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.

The Math
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`
