Please do not comment unless you are making a serious attempt at the problem.

imqwerty · Answer

weight of vol of water displaced = buoyant force

vol of water displaced = vol of body

imqwerty · Answer

$body~fat~fraction ~=~x$
$other~tissue~fraction ~=1-x$
$body~vol = V$

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)*$d_{other ~tissue}$
