Why Does A Metal Ship Float On Water But A Piece Of Metal Cannot?

The weight of the water, the ship displaces is more than the weight of that volume of the ship that is submerged. (accoarding to Archimedes Principle)Archimedes came up with a buoyancy principle, that a ship will float when the weight of the water it displaces equals the weight of the ship and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge.Archimedes continued to do more experiments and came up with buoyancy a ship will float when the weight of the water it displaces equals the weight of the ship and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge. This is kind of a technical way of looking at it. A ship that is launched sinks into the sea until the weight of the water it displaces is equal to its own weight. As the ship is loaded, it sinks deeper, displacing more water, and so the magnitude of the buoyant force continuously matches the weight of the ship and its cargo. 

An object will float so long as it is lighter than the water it displaces. Steel is denser than water, but a steel boat is mostly hollow. The hollow sections are filled with air which is much lighter than  water, so the average weight of a steel boat is much less than the water it displaces.

A steel boat can float in the water because when steel shaped into a boat it displaces more water then it weight thus making it buoyant. This is the basic Archimedes principle.

Ships are made heavy metals because due to heavy metals the Buoyant Force is stronger on ship that's why ship float on water because ships are designed in such a way that buoyant force is always stronger as compared to the weight of the ship.

Metal sinks because of the way it's shape is and also the amount of the weight. A ship does not sink because, the shape is just perfect and the weight is just fine.

It's because of the shape of the ship. If the ship displaces an amount of water, the weight of which is greater than the weight of the ship, the ship being lighter will float. If the weight of the water displaced by the ship is less than the weight of the ship, the ship will sink.

Lol...I don't know I'm trying to get the answer myself. Lol

The air supports it to float.

Becaue the volume of the air the boat withholds and the density vrey complicated

I don't remember the exact amount but for every cubic foot of air space below water level a certain amount of weight is supported by the viscosity of the water.

I need an answer now for the question how do steel boats float on water???

  PLEASE!

The weight of the water the ship displaces is heavier than the overall weight of the ship.

It is because of buoyancy , when the amount of water displaced by the boat is equal to its weight it floats, but the balance comes before the boat fully sinks,when the object's amount of area of contact with water is high it floats than objects having less area.

The average density of the ship (steel and air) is less than that of the water.

Ships are made out of a special type of metal which is designed to float. It is called floatel.
