conversion of ear corn to shelled

Shelled formula;
0.8 X L X W X H = Bu (Rectangular)
0.6283 X Diameter X Diameter X H = Bu (Round)

Ear
0.4 X L X W X H = Bu
0.31416 X Dia X Dia X H = Bu

Close as I can come but looks to me like shelled would be about 40% of ear.

56# kernals = 1 bushel

72# of ear corn = 1 bu of shell corn.

That would mean you throw away 16# of cobs & husk for every bu of shell corn.

On a volume basis, I'm less sure of my numbers. A bu is 1.25 cubic feet? And a bu of ear corn is 1.44 cubic feet I believe????? But my FSA office has used different numbers _every_ time I go there just to play with my mind.... Fresh stacked ear corn occupies more space than old, compressed ear corn. Please don't rely on these volume numbers without someone else saying they are good.
