Hi -

The way you're describing the tank, it sounds like a cylinder.  Are
these the only dimensions you have to work with?

Hello and thanks for the question.

The volume of a cylinder is calculated as follows:

radius of the base squared x Pi x the length of the cylinder.

If the circumference of the cylinder is 80 inches, that means the
radius of the base is:

Circumference / (2*Pi) = Radius

Radius =  12.73

We can now calculated the volume of the cylinder:

12.73 inches ^2 * Pi * 160 inches = volume

Volume = 81,487.33 cubic inches

There are 231 cubic inches in a US gallon.  

This means that your tank will hold: 352.759 gallons
