Question

Why a boat floats whereas a a nail sinks in water​

Answer 1

Answer:

$\sf\fbox\red{Answer:-}$

The density of iron is more than the density of water

Answer 2

Answer:

The density of iron is more than the density of water, so the weight of iron is more than the weight of water displaced by it, and the nail sinks. Secondly, the boat is hollow and the empty space contains air which makes the average density of the boat less than that of water and hence it floats on water.
