Answer:
80ml
Explanation:
First, you would have to convert your liters to milliliters meaning that 3.2L would turn in to 3,200ml.
Once you get your unit of measurement completely in to milliliters, you can now divide
3,200 divided by 40
This would be 80.
This means that if you distribute 3.2L of coffee in to 40 cups, each cup would have 80ml of coffee.
Hope this helps :)
