Why do wooden rafts float?
Wood’s density is lower than that of water, so a wooden boat will float on the water. Ships are typically made of metal, which is denser than water, and therefore air-filled buoyancy chambers are built into them. This makes the ship less dense than the volume of water it occupies, thus enabling it to float.
