Your question is unclear. Do you mean how many glasses of milk are contained in a 1 liter carton? The answer is that it depends on the size of glasses. A "glass of milk" is an indefinite measure. Glasses come in different sizes. Larger glasses hold more milk; smaller glasses hold less milk.
The amount of milk produced will differ depending on the breed of the cow. However, assuming that 20L of milk per day per cow is reasonably average and that a glass of milk is 250ml, one cow would produce around 80 glasses of milk daily.
8 16oz glasses
Two 8 oz glasses of milk will come in 1 pint
A cow can produce 350,000 glasses of milk in its life.
It varies, maybe 2 or 3 glasses of milk.
A standard drinking glass holds about 250 ml of liquid. There are four standard glasses of milk in a liter.
That is 8 of them.
That all depends on the average lifespan of such a cow. For most cows, they will produce two or three calves before they are culled for lowered productivity. However, a fair number of dairy cows will produce over 8 to 10 calves in her lifetime if she's able to be productive and live to over 10 to 15 years of age.
