 The Temple's Chambers

Before the length of an hundred cubits was the north door, and the breadth was fifty cubits. Eze 42:2

an hundred cubits... This would be 175 feet.

was fifty cubits... This would be 87 feet 6 inches.

This is not inside the chamber, but at the north gate. This area was 175 feet long by 87 feet 6 inches wide.

The row of rooms… next to the outer court was 87½ feet (50 cubits) long. The other row of rooms next to the sanctuary was twice as long, 175 feet (100 cubits, Eze. 42:8).
