Corner tank volume formula?

[Anonymous]

Anyone know how to calculate volume with a corner tank that is a pentagon?

It's 25 inches tall. Side to first pane is 22 inches. Then three panes come out like part of a hex and are 13 inches each. Then another 22 inch side. From the very front pane to the corner directly behind it is 25 inches.

Any ideas?

You're asking for some hardcore geometry here mayn.....give me a minute.

The footprint of the tank is around 447 square inches. Give or take an inch or two. Since the height is 25 inches, this gives a volume of around 48 gallons.

(Cubic inches/231=US gallons)

HTH.
