The mass of ice lost during melting = mass of water displaced by the ice cube

Therefore, after complete melting of ice, the level of water remains the same.

 

But since the final temperature of water is 4 degree Celcius, the volume of water will decrease for the same mass as density of water is highest at 4 degree Celcius.

 

Thus, the level of water falls.
