Homework Help: Physics

Posted by ana on Tuesday, November 17, 2009 at 4:52pm.

A 10cm times 10cm times 10cm wood block with a density of 700kg/m^{3} floats in water. What is the distance from the top of the block to the water if the water is fresh?

weight= density*volume*g
weight=700*(0.001)*9.81
weight=6.86newton

weight=densitywater*g*10cm*10cm*depth
6.86=1000*9.81*.1*.1*d
6.86=98.1*d
d=.0699...which is wrong
i have to get an answer in cm.
