A cylindrical cup is 8 cm in diameter and 20 cm tall and is filled halfway with saltwater. The density of the saltwater is 1.1 g/cm^3.
A spherical ball has a diameter of 4 cm and a mass of 40g. How much does the level of the water rise when the ball is dropped into the cup?

(In reply to re: My thoughts by Hugo)

But you could add two more balls, diameters b and c say.
