How can i calculate this?
i am doing a maths assignment called rice on a chessboard. i dont know how i would do this question for it (please show working out so i can understand it better.)

calculate how long the amount of rice (2^63 ricegrains) would last a country with the population of 10,589,025.
thankyou so much :)

my teacher said to make it that each person eats 250 for one meal, he said that this was only an estimation.
