If there is enough ice so that its weight causes it to rest on the bottom of the glass instead of floating, then when the ice melts the glass will overflow.
I put ice in a glass. I fill the glass to the top. When the ice melts does the glass overflow?

This is an experiment you can do yourself in about 30 seconds.
Use a glass so you can see to the bottom. Fill it with ice to the top. I don’t care how big the pieces are. Now, start adding water until the water reaches the top.
How much ice is resting on the bottom?
