Half fiberglass half wood volume ?

So after my first box I'm loosing quite a bit of air space and seat position and box wasn't built right, looking to build another box, my question is I wanna do back out of fiberglass to mold to cab and the rest(top,bottom,sides & front out of wood) how would I know it's total volume since it won't be a straight piece of wood for the back?

Use packing peanuts to fill and then transfer to another box to measure
