A 5-pound bag of uncooked rice contains approximately 11 to 12 cups of rice.
This estimate depends on the type of rice, as different varieties have slightly different densities. For example:
Long-grain white rice: about 2.25 cups per pound
Short-grain or brown rice: about 2 cups per pound
Multiply the cups per pound by 5 to determine the total for a 5-pound bag.
