cubic feet always depend of the subs you have, but it looks like a pretty solid design for what we can see from your drawings. 1 cu ft per sub it usually a good place to start and stay in a 'safe zone' for sound quality.

the disadvantages of bandpass is you really limit the amount of tonal fluxuation (not a technical term

) w/ bandpass.. however your bass will hit harder. I prefer sealed boxes for my applications.

the cubic ft is the airspace.. doesn't include the wood. Good way to do it if you have an non rectangular box (which you do) is stuff it w/ cotton or newspaper and take that newspaper and stuff a box w/ it that is the same cu. ft you want.. good luck.
