The other ratio of Revillout and Hultsch, 320 hons = cubit cubed, is certainly approximate.
By the theory of maris 1/5 of 20.6 cubed is 1755; by maris = Assyrian talent, 1850, in place of 1850 or 1980 stated above; hence the more likely theory of weight, rather than cubit, connexion is nearer to the facts.
Sample the eatery's famous sauerbraten, which is made from a not-so-secret recipe of fresh cubed beef, gingersnaps, gravy and fluffy potato dumplings.
The green chile verde burrito, filled with cubed pork in homemade verde sauce is another favorite.
Beside the equivalence of the hon to 5 utens weight of water, the mathematical papyrus (35) gives 5 besha = (2/3)cubic cubit (Revillout's interpretation of this as 1 cubit cubed is impossible geometrically; see Rev. Eg., 1881, for data); this is very concordant, but it is very unlikely for 3 to be introduced in an Egyptian derivation, and probably therefore only a working equivalent.
