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

A cube of iron with a density of 7.87 g/cm3 and a cube of nickel with a density 8.91 g/cm3 may both displace the same volume of water provided they have the same volume.

According to the floatation law, a floating body will displace its own volume. Since the cube of each metal displaced the same volume of water, it means they are of the same volume.

Density is the ratio of mass and volume. At constant volume and varying masses, density would also vary. What it means is that the two substances have different masses but the same volume.
