Okay, so we have a chessboard, it's 8x8, it's got 64 squares.
00:09
We're going to put one grain of rice on the first square, two on the second, four on the third, etc.
00:15
So the last square has 2 to the 63rd grains, which is 9 .223 times 10 to the 18th.
00:27
That's a really huge number.
00:32
The total for all the squares, we have to add all those up, is actually 2 to the 64th minus 1.
00:43
So it comes out to be 1 .84, 5 times 10 to the 19th.
00:53
The volume of a grain is 5 cubic millimeters, which is 5 times 10 to the minus 9 cubic meters.
01:01
So the volume in cubic meters comes out to be 9 .223 times 10 to the 10th cubic meters.
01:20
That's a huge amount of volume...
