How many cups of rice will feed 40 people?

The amount of rice needed to feed 40 people will depend on the serving size and the type of rice being used.

As a general guideline, 1 cup of uncooked rice will yield approximately 2-2.5 cups of cooked rice. For 40 people, you might need around 20-25 cups of uncooked rice, which is approximately 5-6 pounds or 2.3-2.7 kilograms.

It's always best to cook a little extra to ensure that there's enough food for everyone. Additionally, if you're serving other dishes along with the rice, you may be able to get away with using less rice per person.
