The density of iron is 7.87 g/cm3. The density of nickel is 8.91 g/cm3. A cube of each metal is placed into a cup of water. They both displace the same volume of water. How is this possible?

They are more dense than water. This allows the force of bouyancy which is related to the volume of water displaced to be less than the force of gravity which makes the net force downward. The cubes just have to have the same volume to displace the same amount of water because they both sink
