Calculating the volume of a hex tank?

I have a hex. The only way I could figure out what mine was, was to divide the tank up in my head and do the volume of an imaginary rectangle, then do the 2 triangles, and then add the volume together. I hope that makes sense.
 
area of a regular hexagon is (3sqrt(3)/2) * s^2 where s is the length of a side. So, the area of the tank footprint is ~234.5 sq in. Mutiply that buy the height and you get 4455 cu in. 4455 cu in / 231 cu in/gal = 19.2 gallons.

Wow that certainly lost me, Niko's way was much easier.
