I'd have to know the thickness and density of the cotton.

Realistcally, it's more like 1/8 lb per cubic foot. WAY too expensive

13.8 lb/cu ft. 1/8 INCH/cu ft. So, take 13.8/8/12 and that's the density

Density doesn't change with thickness - only weight/mass changes. OC703 is 3lb/cu ft whether it's 1" thick or 6" thick.
