[Verso of Ninth Leaf, Volume II]
If one poppy seed is doubled every day for 120 days, and the cube root of the total number is taken to find the length of one side (of a cubic vessel):
The total number is: 6,646,溝 1,399,穣 7,892,𥝱 4,579,垓 3,645,京 1,903兆 5,301億 4,017万 2,288 grains
(i.e., 6,646,139,978,924,579,364,519,035,301,401,72,288 grains — see annotation)
〔Diagram: Length/Width〕 155,392 ri, 9 chō, 31 ken, 1 shaku, 7 sun, 2 bu, 2 rin, 5 mō (per side)
〔Diagram: Height〕 155,392 ri, 9 chō, 31 ken, 1 shaku, 7 sun, 2 bu, 5 rin
Note: The height represents the depth of one grain (buried).
〔Notes within the diagram:〕
1 ri = 36 chō
1 chō = 60 ken
1 ken = 6 shaku 5 sun
Calculated assuming 4 poppy seeds arranged per bu (of length)
[Recto of Tenth Leaf, Volume II]
The remainders from the above are further processed using the cube root method.
〔Marginal note: The "remainder" refers to what falls short of filling the row of three grains, and so the remainder is again subjected to the cube root method and added in.〕
〔15 ri, 3 chō, 36 ken, 2 shaku, 2 sun, 2 bu — per side〕
〔Remainder: 40 ken, 5 shaku, 4 sun, 2 bu, 2 rin, 5 mō — per side〕
〔Remainder: 8 shaku, 7 bu, 2 rin, 5 mō — per side〕
〔Remainder: 7 bu, 2 rin, 5 mō — per side〕
〔Remainder: 3 bu per side; further remainder: 1 bu, 7 rin, 5 mō per side〕
〔Remainder: 7 rin, 5 mō per side; further remainder: 25 grains remaining〕
If the total number of poppy seeds doubled daily for 120 days is measured using a cubic vessel 100 ri per side:
〔375,214,802 koku, 1 to, 9 shō, 7 gō, 3 shaku, 6 shō, 1 sai, 3 kei, 7 zoku — with remainder〕
