I can't understand why you would even want volume, instead of the two
direct measures of area that you have. In any analysis you could easily
use the two measures as probably two independent variables, and they
would provide you more information than the "volume" you are after.
After all, a million different shapes can have the same volume, but the
unique areas in two dimensions are going to be unique for each thing
being measured.
