Archimedes' Principle: Ice in oil


A glass beaker contains two oils. Caster oil with a density of $\rho_{c}=956\,kg/m^3$ fills the lower portion of the glass and almond oil with a density of $\rho_a=921\,kg/m^3$ fills the upper portion of the glass. An ice cube with density $\rho_{ice}=934\,kg/m^3$ is placed in the glass and slowly descends until it stops at the interface between the two oils.

What fraction of the ice cube's volume rests below the interface?

Write the fraction of ice below the interface to two significant figures.

Where does the ice cube float? Created for Copyright 2016. All rights reserved.
