Why do a cricket ball float in water even though it is a heavy object?

According to Archimedes Principle, the buoyant force exerted on a fluid is equal to the weight of the fluid displaced. So, when an object is placed in water, it will displace its weight in water. The ball has air-filled in it. As air is denser than water, the ball takes up more space than the volume of water it displaces, so it floats.
