How were the pyramids built so accurately?
But what the Egyptians lacked in tools, they made up for with science and engineering precision. Smith explains that they developed and used the cubit rod to measure and lay out the dimensions of the pyramid; a square level to level horizontal surfaces, and a 3:4:5 framing square to create precision 90-degree angles.
Could pyramids be built today?
