weight of vol of water displaced = buoyant force vol of water displaced = vol of body

\(body~fat~fraction ~=~x\) \(other~tissue~fraction ~=1-x\) \(body~vol = V\) fraction of volume of fat = V*x fraction of volume of other tissue = V*(1-x) body weight = V*x*\(d_{fat}\) + V*(1-x)*\(d_{other ~tissue}\)
