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.

  • Physics -

    I bet it wants the distance in cm... 6.99 or rounded to 7 cm.

    Works looks right

  • Physics -

    its asking for the water level from the top. so just subtract 7 from 10 and we get 3cm!

    THANKS TO The anonomyous person who cleared this question up its been bothering me for days!!!

  • Physics -

    thanks....u really helped a lot...people have to specify when helping out someone
