Hi!
Here's one problem.
A piece of iron(with cavities) weighs 6000 N in air AND 4000 N in water.The density of iron is 7.87 g/cc.What is the volume of cavities?
My assumption is that the weight of water displaced is equal to the buoyant force(which is right because Archimedes said so). The problem is what volume of water is displaced? Is it right to say that the volume of the iron piece without the cavities is the volume of water displaced? :uhh:
