## Homework Statement

A cube of some unknown material floats in a pool of mercury. 43% of the cube is above the surface. Find the density of the cube.

## Homework Equations

Fb=pVg

d=m/V

## The Attempt at a Solution

So I Googled the density of mercury and found that it is 13,594 kg/m

^{3}. I also know that 57% of the cube is underwater.

mg=pVg

m=pV

m=p(.57V)

d=m/V

d=p(.57V)/V

d=.57p

_{Hg}

Is that correct?
