The average human has a density of 950 kg/m3 after inhaling and 1018 kg/m3 after exhaling.
(a) Without making any swimming movements, what percentage of the human body would be above the surface in the Dead Sea (a lake with a water density of about 1230 kg/m3) in each of these cases?

    Let V be the volume of the body.

    Let v' be the volume of the body displaced.


    densitywater*v'=densitybody*V

    solve for v'/v
