【Volume 4, Folio 27 verso】
△ Starting with 1 poppy seed and doubling it every day, one asks how many seeds there would be after 120 days of doubling:
6,646 kō · 1,397 jō · 7,892 jo · 4,579 gai · 3,645 kei · 1,903 chō · 5,301 oku · 40,170,000 · 288 seeds
(i.e., 6,646,1397,7892,4579,3645,1903,5301,4017,0288 seeds)
This number can be determined through calculation on the abacus (soroban). However, since it is difficult to grasp just how large this number is, one may ask: if these seeds were stacked into a cube, how large would it be?
155,392 ri, 9 chō, 31 ken, 1 shaku, 7 sun, 2 bu, 7 rin, ■ mō on each side.
【Volume 4, Folio 28 recto】
One ri is 36 chō.
One chō is 60 ken.
One ken is 6 shaku 5 sun.
This is calculated on the basis of 4 poppy seeds arranged per bu (side by side).
Height: 155,392 ri, 9 chō, 31 ken, 1 shaku, 7 sun, 2 bu, 7 rin, 5 mō
Width: 155,392 ri, 9 chō, 31 ken, 1 shaku, 7 sun, 2 bu, 7 rin, 5 mō
