Alan politely corrected my fallacious memory "For a normal Langstroth Deep
with available frame area of 8 1/8" x16
5/8" and 22.7 cells  per sq. inch, the total cells will be 8 1/8 x 16
5/8  x 22.7 cells/sq in. x10 frames x 2 sides per frame  =61325."

Curious matter...Alan's comments made me go measure some undrawn foundation.
It turns out I am using foundation with an area of only 7 15/16 x 16 9/16
(apologies to those on a metric system).  Much more important, once the
thickness of the cell wall is taken into account, I only get 14 cells a sq.
inch.  (Compared to Alan's 23!)  I checked measurements many times!

Given the 23 day brood cycle, this leads little extra room whether 9 or 10
frames are used.  I have never understood how beekeepers can limit the brood
nest to 1 deep and this detailed check reinforces my lack of understanding.
I admire those who do so, as there are lots of advantages to the beekeeper,
but don't understand how it is possible.
