A cube of ice whose edge measures 20.8 mm is floating in a glass of ice-cold water with one of its faces parallel to the water's surface. How far below the water surface is the bottom face of the block?

## Homework Equations

P=F/A, P2-P1=[tex]\rho[/tex]gh

## The Attempt at a Solution

so i first found the surface area of the cube which was 2.59584m [using the formula 6*x

^{2}]

then i thought abt equating P1= 101.3 x10

^{3}Pa. and solve for h but i don't know what to put for P2..pls. help
