measured with a precession tool instrument.






Think of it as a geometric reality. In order for the lid to be square with the two inside walls, the inside walls would have to be parallel to one another along the vertical axis.


Moreover, the topside of the box would need to establish a plane that is square to the sides. That makes finishing the inside exponentially more difficult.


The manufacturers of these boxes in the Serapeum not only created inside surfaces that were flat when measured vertically and horizontally, they also made sure that the surfaces they were creating were square and parallel to each other, with one surface, the top, having sides that are 5 feet and 10 feet apart from each other.

But without such parallism and squareness of the top surface, the squareness noted on both sides would not exist
