Ok, Scott - I went back and figured out what the problem is.
You are correct regarding a freshwater ice cube in a glass of fresh water with equal densities for both.
I am correct regarding a floating ice cube (or iceberg) with any degree of fresh water in the ocean raising the sea level more than it displaces.
My mistake was in applying what I know of ice bouyancy/density of icebergs to a freshwater ice cube in a fresh water glass (not many of us drink glasses of saltwater). Roughly 11% remains above water whereas an ice cube of equal density to the water in a glass has a little less than 9% above water.
Sorry about that...Does it make more sense now?
I suppose that is what I get for doing my own homework rather than just copying and pasting someone elses...  
Steve
