Suppose you have an open topped box that is 5cm x 5cm x 5cm. (capacity: 125 cubic centimetres) Inside the box is a steel ball bearing that is 25 cubic centimetres in size. Next to the box is a two-liter pail filled with mercury. How many cubic centimetres of mercury would you have to pour into the box to completely submerge the ball bearing?


You couldn't. Mercury is so dense steel floats in it.
