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*(10^-3)*9.81
weight=3418.877985

weight=densitywater*g*10cm*10cm*depth
3418.877985=1000*9.81*.1*.1*d
d=34.85
it is't working...what am i missing?

    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 still wrong
    i have to get an answer in cm.

    plz help
