what determines if something floats?

ocean

the density is 1.428 X 10^-3 kg/m3 for the wood, so it will float right completely above the ocean surface?

is this right-??

Volume submerged = Density of wood / Density of oceon water?

have you ever seen something float right on the ocean surface?

the submerged volume = the volume of water displaced.
right?
if you put a rock in a container of water, the water level rises.

now, what does displacement have to do with floating?

in this case i got the density of wood more than that of that oceon so i think it will sink!

how did you get the density for wood? do you have the right units?
