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(2): My thoughts by Sir Percivale)

And put them in a bowl, instead of a cup.  Then ask, "How high would the water level rise above each point of contact between a ball and the surface of the bowl."
