Expert Answer:

We know that the density of the ice cube is less than the density of water and the ice cube floats. So when ice cube is placed in a beaker completely filled with water it will float and displace enough water (that drops out) to support its weight. As the ice starts melting, it will turn back into water and fill up only the volume that it displaced earlier. So, the water level in the glass remains the same.
