Re: 100 lb of Lead Vs 100 lb of concrete
Yes, it is correct. It is all about density. Water has a density of 1g/cc. Anything that is less dense than that will float. Anything that is more dense will sink. If something sinks, it will weigh less than it does in air because water has a relatively high density and the relative density is important. The denser something is, the less water it displaces so it will weigh more.
