Answer 2

Answer:

when you put a steel pin in water it sink, but a ship made of steel floats because steel is denser than water, so steel pin sink but a ship also made of steel float . It has a lot of hollow spaces filled with air, this increase the average volume of ship .When volume increase density decrease , hence the ship floats.
