Question
Why does a ship made of iron and steel float in water whereas a small piece of iron sinks in it ?

Solution
Iron and steel pieces sink in water because iron and steel have higher density than water, but iron and steel ships float in water because they trap a lot of air and thereby reduce the average density of the ships (steel and iron) than water.
