Because it is less dense than the water/liquid.
Sometimes it's not obvious, but gases have weight. The weight of all the air above you is called the barometric pressure. Each gas has a different weight. Hydrogen is the lightest gas so it floats on heavier gasses, just as wood floats in water. Helium is also lighter than air. That's why balloons are filled with helium, so they float in the air.
because the breth in lots of air and air floats because the breth in lots of air and air floats
A balloon.

Because the air contained inside the matress is lighter than the water, it floats. same reason why Helium, which is lighter than the rest of the air around it, floats as well when it is in a balloon.
AnswerThe air in the ship PLUS the weight of the ship must just equalthe weight of the water displaced (pushed out of the way)by the hull of the ship.The pin lacks the air.
because a soda can is full of air. Air is lighter than water, and is therefore boyant and the can floats.
Beautiful music floats
The float has air in it.
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
A wooden boat floats in water due to its buoyancy and the displacement of water created by the boat's weight.
Weight of ship = weight of (displaced) water.
