(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Buoyant force. A block of wood floats in

oil with 90.0% of its volume submerged. What

is the density of oil? The density of the block

of wood is 0.67 g/cm3.

2. Relevant equations

buoyant force = pgV

3. The attempt at a solution

p(oil) V(oil)=p(h20) V(h20)

p(oil)= p(h20) V(h20) / V(oil)

i know that the V(oil) displaced is equal to .9V(h20)

so, p(oil) = .67 V(h20) / .9 V(h20)

do the terms 'V9h20' simply cancel, leaving me with .67/.9? Thanks
