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

An iceberg is floating on sea water such that only 10% of its volume is above the water level. What is the density of sea water expressed in terms of the density of ice.

2. Relevant equations

[tex]\frac{Vf}{Vi}[/tex] = [tex]\frac{\rho}{\rho}[/tex]

[tex]\rho[/tex]_{f}= density of sea water

[tex]\rho[/tex]_{i}= density of ice

3. The attempt at a solution

I know this is a rather simple problem but where I am getting hung up is the ratio of the visible portion of the iceberg. I hate to admit but the simple maths trip me up. I began by isolating the eq so that:

[tex]\rho[/tex]_{f}= [tex]\rho[/tex]_{i}[tex]\frac{Vi}{Vf}[/tex]

from which I get [tex]\frac{9}{10}[/tex] [tex]\rho[/tex]_{i}

By the way this is an even number problem so I cannot look up the answer, so is this correct?

Thanks in advance.

Joe
