Chessboard Parable. Use the chessboard presented in the text. Assume that each grain of wheat weighs 1/7000 pound.

How many grains of wheat should be placed on square 16 on the chessboard? Find the total number of grains and their total weight (in pounds) at this point.

The answer for this is 32,768 grains; 65,535 grains; about 9.36 pounds is the answer for this.

What is the total weight of all the wheat when the chessboard is full?

2.64 8 * 10¹⁵ pounds is the answer for this question.

The total world harvest of all grains (wheat, rice, and corn) in 2016 was about 2.5 billion tons. How does this total compared to the wheat on the chessboard?(1 ton = 2,000 pounds).
