Density is how much mass is compressed into a state of volume. Considering bread is made of water, carbon, and other light molecules, it doesn't have much mass. Steel has much more mass and thus will be more dense; however, if u can compress the bread until it has the same mass at the same volume of the steel, it will have the same density.
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
That could be ANY substance whose density is greater than 3 grams per cm3. Examples include but are not limited to mercury, copper, gold, iron, lead, platinum, uranium, brass, silver, and steel.
The answer depends on the grade of the steel, but 7.85 g/cm3 is generally accepted for plain steel. If the steel has added alloying elements such as tungsten, then it can be as high as 8.05 g/cm3

A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
Steel has the greatest density of the three.
The greater the density, the faster the wave moves. Sound (a wave) travels faster in steel than in air. Steel has the higher density.
Steel don't float on water because the density of steel is greater than the density of water.
It's possible that a ship of steel will not sink as well. But if it will sink, it would be because the density of steel is greater then the density of water, while air's density is lower then water's.
Steels density is greater than water
The speed in steel is much greater because, although the density of steel is greater than air the forces are much greater. Check out Wikipedia.org, "The World's Encyclopedia" http://en.wikipedia.org/wiki/Sound#Speed_of_sound
Tin is a metal, so your question is nonsensical.
Steel, The greater the density, the faster sound travels through it.
The steel has a density greater than water; but the ship does not. To calculate density, you divide mass by volume. This includes the mass - and the volume - of any air trapped inside the ship.
There is air in the boat so the overall density is less. The weight is spread out.
You can infer very little about the density of the substance. Ships made of steel, with a density much greater than that of water, can float.
density is a physical property of the material, it has nothing to do with the size of the piece. lead is 11.35 g/cc iron is 7.874 g/cc steel is between 7.75 and 8.05 depending upon type of steel.
