Calculating DM/cu' in Silage bales

Dumb question I imagine.  Second guessing myself.  

 

% moisture converts directly to weight?  For example a 4x5 bale weighing 1413 lbs. @ 50% moisture would have DM content of ~706 lb.

 

New to wrapping baleage, planning on custom work  and trying to calculate how to know if DM/cu' is within recommended range of 10 to 15 lb. DM/cu'.

 

Created the attached grid in excel to be able to help customers approximate where they are at.  Data can be changed in the Bale size and % moisture cells.

 

According to the grid, the above example would estimate 12 lb. DM/cu'

 

 

Thanks in advance!
