The building that faced the courtyard on the west side was seventy cubits in width

This can be stated as a separate sentence. Alternate translation: "There was a building on the west side of the temple area, and its entrance was towards the courtyard. It was seventy cubits in width"

seventy cubits ... five cubits ... ninety cubits

Each long cubit was about 54 centimeters. See how you translated this in Ezekiel 40:5. "70 cubits ... 5 cubits ... 90 cubits" or "about 38 meters ... about 2.7 meters ... about 49 meters" (See: rc://en/ta/man/jit/translate-bdistance)
