grouping sugar factors at the sugar factory

I'm down to our last sugar cube, my team having eaten 251 of them. It seems a good number to have had in so surprisingly short a time. I hear the first cubes (a pink and white present!) came by the 350, and their commercial successors by the 250. I'm curious which of their respective factors (2*5*5*7 and 2*5*5*5) got paired to make a box. Ours (C&H) could have been 4*7*9 and brought the wrapper closer to a fold-out cube-eater's progress-bar, but 3 met 4 instead to make a nice tissue-box of 3*7*12.
