Dimensions = Gallon formula?

[Marc118]

Im looking for some type of formula that will allow me to calculate the # of gallons a tank will have. Basically taking any given dimensions and getting its fluid capacity.

I plan on building a new tank soon.

Also what is the desired thickness of acrylic for a tank? .5"?
