    Why Captain? Because it's a side multiplied by a side squared?

    Hmm, didn't see that one.

    yeah, it kind of looks like the volume of a cylinder to me (with height = 3b and radius = c), but maybe Captain was thinking of something else

    May be I'm thinking of dimensional analysis. Case 7 is [L][L]^2 = [L]^3 which
    is all that is needed for it to be a possible volume.

    Of course, any of them can have "hidden" units, where the constant (such as the \pi) carries a unit with it...
