Why float the boats?
The boats float because are less dense than water. It's true that majority of boats are of metal, but these occupy great volume.
but, What is density? is the quantity of matter than exist by volume unit. One sphere of 1m cubic of iron, no doubt will go to bottom of sea, but if with that same meter cubic of iron we build an hollow sphere, it volume will be greater than solid sphere, and with the help of the water from upwards, this will float.
