If there’s water in a jug and ice added the the jug to the absolute brim where the ice is coming out over the surface... when that ice melts, how come it doesn’t overflow??

ice has more surface area than its equivalent amount of water (molten ice), but both have the same volume (volume cannot change). as ice is lighter and appears "bigger" than the amount of water used to make it, it floats around on the surface, taking up the same volume in the jug as it would melt. thus, the ice melts and its surface area changes, but volume doesn't. thus, water from molten ice doesn't overflow in the jug

Thank you.

Because the amount of water displaced by the ice is roughly equal to the mass of water that forms when the ice melts.
