Because the material used to build them is formed into a shape that will displace a
lot of water. As the shape settles into the water, once the weight of the displaced
water is equal to the weight of the object, the object floats at that depth and doesn't
settle any further. If the material were all rolled into a solid lump, it would displace
much less water, and would sink like a rock.

Would a large metal ship float in the same volume of fresh water?
Metal ships are built to float.
Why should a boat made of metal float?
The size of the boat is equal to the water displaced by the boat. This means, if the boat is bigger then its weight, the boat will float. If the boat is smaller than its weight, it sinks. This is why metal ships are so big.
Why does a penny sinks in water whereas ships doesnot sink in water?
All pure metal sinks, only by entrapping air in waterproof compartments can you make it (ships) float.
Can you make metal float?
You can't make a bar of metal float on water, but boats with metal hulls float. Also, metal bars and other metal objects float on mercury.
Can metal ships float?
It depends. A steel ship will float just fine, so will an iron one(i.e. Old Ironsides). It all depends on the size, weight, and buoyancy of the ship.
How will you determine if something will float in water?
If the object, when submerged in water, displaces a volume of water whose mass is greater than its own, then it will float. The density of the material from which it is made is not the key as can be seen from the fact that ships made of metal will float.
How cruises ships float?
Cruise ships float with help from density and a principal called buoyancy.because of greater surface area.
How do they get large cruise ships into the water after building?
The ships are built in drydocks which can be flooded to float the ships out.
How ship float on water?
Ships, whether made of wood or metal, have a lighter specific gravity than water. Ships actually displace the water rather than floating on it.
Why ships float?
The main idea at work is the upward force of fluid that opposes the gravitational pull on an immersed object, buoyancy. Water pushes the ship upwards.In Earth, fluid experience greater pressure the further we go down. This is why we cannot simply go to the bottom of the ocean with a wooden barrel-it will be crushed by the pressure exerted by the water if it will go deep at all. This pressure forces things to go up. And, this force is directly proportional to the weight of the water. This means that things denser than the water will go down. Ships today are made of metal which are denser than the water however, the ship is not composed of only metal. Ships also contain air which is less dense than water. Ships contain more air than metal to decrease its density and become less dense than water to float on it.
Are aircrafts the same as ships?
No, ships float on the sea, aircraft fly in the air. NO similarity.
Can any kind of metal float?
Yes, provided you have the metal in a solid form which can be shaped so it will float, and a substance which it is liquid enough to float in at that temperature.
