simple volume..(area of the base)x(the height)->(pi x r^2)x(h)...since there's 3, multiply that final number by 3.

Make sure you use the outer diameter of the port, not 4", which is the inner diameter. Might not make a big difference with Aeroports, but if you use PVC ports, that 1/4" wall can start to add up when you start adding port area...
