...if you fill a glass with ice cubes and water, when the ice cubes melt, does the glass overflow

I'm not Al, but yes, it does when the glass is full and a significant amount of each ice cube protrudes above the surface.

Wrong. Ice floats because it displaces a volume of water equal to its weight. So if the ice melts, its volume reduces to the initial displaced volume - so the water level does not rise.

Make sure you have your own facts straight first.

I am not so sure that is true. I have done the ice cube/glass of water thing in the past and the water level always fell.

I shall redo tonight and cram with as much ice as I can and get as much ice above the water as I can. But I will not pile ice ontop of ice already protruding from the water. With careful balance, you could easily stack far in excess of the glasses capacity just in ice out of the water.

Not if all of the ice was initially floating, and the water is still “ice” cold.
