A person's density 980 kg/m3 is floating in salt-saturated water if density 1210 kg/m3.
1. what percentage of the person's volume is submerged?
2. what percentage of the person's volume is above the surface?
I found the percent submerged by doing Vsub/Vob, and got that the object is 80.99% submerged. I can't figure out how much is above the surface?

1. what is 100-80.99 ?
