Assuming there is enough ice to cover the top third of the glass and all ice cubes start off with similar sizes, those at the bottom of the 'group' of ice are in contact with water fully at the initial room temperature(I assume). They will absorb heat from ~25°C water via conduction. read more

If you put a few ice cubes into a glass of warm water, you should already know the result: the water will cool down and the ice cubes will melt. In this case, there is enough water at a high enough starting temperature to not only increase the temperature of the ice cubes, but also melt them. read more
The space taken up by the object under the water is same as the amount of water of the same weight. So in ice cube terms: the volume of the water that the ice cube displaces is the same as the weight of water in the ice cube. Given that these two are exactly the same, the level therefore remains constant. read more
