Roughly 20 years to build the Pyramid of Giza.
Tutankhamen didn't build a pyramid at all.
The biggest pyramid is the Great Pyramid of Giza. This pyramid is the oldest and largest of the 3 pyramids in Giza. It is the oldest wonder of the ancient world. This pyramid was the tallest man-made structure for many thousands of years. This pyramid was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu. He was the second pharaoh of the fourth dynasty. Hope this helped :))
About 6,000 to 10,000 people.

The Pyramid of Giza was built on 2560 BC. Mexico's Pyramid of the Sun was built on 100 AD. There is a difference of more than 2600 years among both pyramids.
On a three-dimensional pyramid there are 5 faces, 8 edges, and 5 verataces. I hope this helped! :)
There are many different theories about the purpose of the Great Pyramid. Along with not being able to conclude absolutely who built the Great Pyramid, mankind also does not understand why it was built. Many believe that Pharaoh Cheops (or Khufu) built the Great Pyramid for his tomb around 3350 BC, because many of the other pyramids in the area have been found to be burial chambers for the various kings of Egypt. Now, there are some that believe the Great Pyramid monument was a time capsule left by an advanced civilization. There may have been some leaders of this civilization wanted to leave a message to future civilizations. Others think it was some civil service project.
The bent pyramid
It all depends on the size of the pyramid. The ancient greek historian Heroditus (c.450BC) was told by his guide that the Great pyramid at Giza took 100,000 slaves and 20 years to build.
