how much of ice cubes (in liters, ml, or oz) goes into a tall (12oz) size cup?

That depends alot on the type of ice.

Solid ice has a density only slightly less then pure water. 0.92 kg/L as compared to 1 kg/L for water.

Crushed ice has a density of about 0.5 kg/L, half of the density of water. (I found data listing it anywhere from 0.5 to 0.59 kg/L)

So a 12 ounce cup full of crushed ice would contain about 6 ounces of water when melted.

Actually, it is a little more complicated than that. Depending on the size and shape of the ice, as well as the shape of the glass, you can end up with more space than ice. Best way is to weigh the ice if you can. Water is about 8 lbs per gallon, which works out to about 1 oz per 1 fl oz. Weigh the empty glass, then fill it with ice and weigh it again. The number of oz difference is basically the fluid volume of the melted ice.
