How many cups of rice will feed 100 people?

The number of cups of rice required to feed 100 people depends on several factors such as the type of rice, the portion size desired, and the presence of other dishes or accompaniments. Considering an average portion size of about half a cup of cooked rice per person and assuming we're using long-grain white rice, here's a rough estimate:

1. Uncooked Rice: If you start with uncooked rice, you will need to account for the fact that rice expands when cooked. Typically, 1 cup of uncooked rice yields approximately 2 cups of cooked rice.

- For 100 people, you will need 100 * 0.5 / 2 = 25 cups of cooked rice.

- Since 1 cup of uncooked rice makes 2 cups of cooked rice, you'll need 25 / 2 = 12.5 cups of uncooked rice.

2. Cooked Rice: If you already have cooked rice, the calculation is simpler.

- You'll need 100 * 0.5 = 50 cups of cooked rice.

So, to summarize:

- If you're starting with uncooked rice: you will need approximately 12.5 cups of uncooked rice to feed 100 people a half-cup portion of long-grain white rice each.

- If you already have cooked rice: you will need about 50 cups of cooked rice.

Remember, this estimate can vary based on the type of rice, cooking methods, and individual preferences, so it's always a good idea to adjust the quantity as needed.
