Buoyancy is determined by the amount an item weighs vs. the weight (of water) it displaces. If a ship or other item weighed 10 lbs, it must, by its shape be capable of displacing 10 lbs of water. If it displaces more, then a load factor can be determined. You can make a floating vessel out of almost anything as long as the rule above is true.

even a huge ship with all it's steel is lighter than the weight of the water it displaces, so it will float, as long as water can't rush in to the void in the hull of the ship.
Water is extremely dense - just think about how much a single gallon of water weighs......
If you properly shaped a small piece of iron like a boat, it will float too.

If the shape of the hull allows a ship to displace a weight of water greater than the weight of the ship, it will float. It has to do with shape. They even make boats out of cement.

The piece of iron is no engineered to float. It is not hollow or fashioned to displace water without sinking to the bottom.

The reason the hull takes up so much room is to displace an amount of water that exceeds the weight of the boat. If the hull springs a leak, the boat will sink.

hey a steel ship floats because even thou steel weighs 700 lbs a square foot and water weighs 62.4 lbs a square foot the ship displaces more weight then it actually weights. like an air craft carrier is so massive and huge it displaces allot of water allot more then it weighs so it floats even thou the components in it do not.

The iron is shaped so it captures air, which is lighter than water. If you put a hole in it and water comes in and pushes the air out, the boat wil sink just like in "Titanic"

if some thing wieghs less than the water it displaces it will float. ther are ships made of concrete out there. its the shape

I wish I could help you...I wonder how ships float all the time...its truly amazing...along with huge airplanes flying and all that stuff. Its incredible.
