If an ice cube is placed in a cup of water and 15% of it is above the water, what is the approximate density of the ice cube (assuming the density of water is 1000 kg/m^3)? And how much did the water expand as it froze? Explain how you determined this.

So, to find \(\rho_{ice}\) the two forces must be equal since ice is in static equilibrium.

So I should set them equal to each other? And what is V standing for here?

Volume of the ice cube. It'll cancel each other, so don't worry.

Oh, ok. So I do set them equal to each other?

So it ends up being .85 * 1000 kg/m^3?

It seems correct. Rho of ice is less tha rho of water.
