A piece of driftwood floating in the ocean has 35 percent of its volume above water. What is the density of the driftwood if the ocean has a density of 1,025 kg/m^3.

2. Relevant equations

ρvol(driftwood)=ρvol(ocean)

3. The attempt at a solution

Well based on a problem we did in class I attacked it this way.

Since 35% is above, I would assume 65% is below, giving me ρ.35=1025(.65).

Then ρ.35=666.25 so ρ=1903.57 kg/m^3
