Plan

1. Get all the material property values of all materials planned on being used (density mainly)

   1. Basswood
   2. Polplar lite Plywood
   3. Foam board
   4. Monocote
   5. Balsa
   6. Aluminum

2. Calculate the volume of each component

   1. Exterior Side panels (Basswood or plywood)
   2. Interior side panels (Balsa or basswood)
   3. Bulkheads (Balsa or basswood)
   4. Floor panel (Plywood or basswood)
   5. Skin (Foam panel)
   6. Stringers (Small wooden dowels)
   7. Booms (Aluminum)

3. Multiply by density to get mass (check units)
