A merchant had 10 barrels of sugar, which he arranged into a pyramid as shown in the illustration. Each barrel, except one, was numbered. The merchant accidentally arranged the barrels such that the sum of the numbers along each row equaled 16. Could you rearrange the barrels such that the sum of the numbers along each row equals the smallest possible number? Note that the central barrel (which happened to be number 7 in the illustration) does not count in the sum.
