Can pyramids be built today?
To build such a pyramid today (using modern technology and equipment such as cranes and helicopters), it would take 1,500 to 2,000 workers around five years, and cost around $5 billion.
How were the pyramids built so perfect?
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.
