    There is no formula for figuring out an unubtanable solution.

    But you can fill the mold with a solid substance and measure it. Dump a pound of sand in there and go from there...

    Edit - If you need to know how big to make it before hand just rough estimate the dimmensions. And work from there.

    Re: Box size help

    Now if it comes out under or over the airspace specs, am I SOL, or is there a way to correct it?

    Adding a solid item, say 2x4 wood or left over MDF laying around will decrease the internal volume.

    For a box to small, adding some polyfill will help.
