Title: Corpse volume increased

So in DDA human has mass of 81 kg. And human body has volume around 65 l.
Volume to mass coefficient will be about 3.25 (for flesh). And for water it is 4.
It a bit off, as flesh to water density is 1.4, so I took 3 as coefficient.
Tiny (1kg):
2 --> 3 vol. (frogs, bats, cats, racoons)
Small (40kg):
40 --> 120 vol. (children, beaver, dogs)
Medium (81kg):
75 --> 250 vol. (humans and all kind of zombies)
Large (120kg):
160 --> 370 (bear, moose, fat zombies)
Huge (1400kg):
600 --> 3500 (hulk, tank) (should be 4200, but for space limit assumed they have denser material.
Also some containers to compare:
duffle bag - 120 vol.
beer keg - 200 vol.
barrels - 400, 450, 825 vol.
