A peasant had the wonderful good fortune to save the life of the King of Siam.
The King in turn, granted her payment in any form she wished. “I’m a simple woman,” said the peasant; “I wish merely to never be hungry again.”
The peasant asked to have payment made onto a huge chessboard painted on the floor. Payment was to be as follows: one grain of rice on the first square, two grains on the second square, four grains on the third square, eight on the fourth, etc… until all 64 squared were filled.
How many grains of rice will the peasant receive from the King? Roughly what volume of rice is this?
