Question

You have a steel ball that has a mass of 6.0 kg and a volume of 3.0 * 10^-3 m^3. The density of the steel ball is 2.0 g/cm^3. How can this be?

Answer 1

This can be because the density of steel is 7.8 g/cm^3, which is much higher than the density of the steel ball. This means that the steel ball must be composed of a different material, such as a lighter alloy, or have a different shape than a solid sphere, such as a hollow sphere.
