Did it take 20 years to build the pyramids? While the pyramid was originally built by 4,000 workers over the course of 20 years using strength, sleds and ropes, building the pyramid today using stone-carrying vehicles, cranes and helicopters would probably take 1,500 to 2,000 workers around five years, and it would cost on the order of $5 billion, Houdin said, ...
How long did it take to build the oldest pyramid?

Why did it take so long to build a pyramid?
The Construction Process According to estimates, each pyramid took 15 to 30 years to be built. The varying sizes range from 1.2 million to 92 million cubic feet, and due to the primary ingredient being massive limestone blocks, it is understandable that some pyramids took longer than others.

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.
