Adam Clarke on Ezekiel 41:13

So he measured the house - The temple, taken from the wall which encompassed it from the western side to the vestibule, was one hundred and one cubits; five for the separate place, nine for the wall and the chambers attached to the temple, sixty for the sanctuary and the holy place, ten for the vestibule, and twelve for the two great walls on the west and east of the temple; in all, one hundred and one cubits, See the plan, GHI.
