I think that an extra '1' got appended before the "5,000" above.

There are about 25 cells per square inch on each side of a typical comb with
5.3mm cells. (See
http://www.internode.net/honeybee/Misc/CellCount.htm for other sizes of
cells).

Each side measures about 8" x 17" or 136 in^2

That gives 136 x 25 = 3,400 cells per side -- or 6,800 cells total per
frame.

Seldom do we see every cell filled with brood, therefore 5,000 is a
reasonable estimate for a nice frame of brood.
