That is an agressive estimate. The USGS site has this:

What I was saying in my last post is: you can only add a certain amount of ice cubes to a glass before the water level in the glass changes.
According to this site,
elmhurst.edu
If the volume of melted water from added ice cubes is more than 9% of the volume of the water in the glass, then the water level of the glass will increase.
If I still cannot make myself understood, then I give it up<g> |
