In fact, the density would have to be less than the density of water, i.e., less than 1 g/cm3. Density is mass divided by volume, so the ship would have to have a large volume.
When the ship's volume displacing water (immersed volume, when not 'leaking') is greater than 46328 (Mega gram) / 2 (Mega gram/ Mega cm3) = 23164 (Mega cm3) = 23164 m3 then the density is less than 2...
For a ship, the average density is the relevant thing. The ship has volumes filled with air, and other things - not just the steel hull. If the average density is less than that of water (1 gram per...
Density = Mass / Volume. This formula is true no matter what values you have for the object's mass andvolume. It makes no difference whether the mass is "less than" or "greater than" the volume (the...
