In addition, they used stone like granite: a material so hard that it wouldn't act like a sponge – the water didn't penetrate it. So, the stone would shed the water and the building would last longer.

It turns out it is really, really hard to demolish a mountain, which is what the pyramids essentially are. Man made mountains holding the bodies of kings within. You can't smash the base because these structures stand on compressive strength.
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, ...
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.
Several Muslim leaders such as the Caliph Yazid III ordered the destruction of all the pharaonic monuments. However, there is considerable evidence of popular local pride in monuments such as the Giza Pyramids and the Sphinx, so much that these monuments were never destroyed out of the fear of causing riots.
Although it's believed that these structures hold some ancient secrets of the ancient Egyptian pharaohs, scientists have not been able to discover much. There are still questions left unanswered, and we are still waiting to know more. Also, there are interesting facts about these ancient marvels that you need to know.
When it was built over 4,500 years ago, the pyramid of Khufu stood at 481 feet tall. But over the years, erosion has caused the pyramid to shrink down a bit. It now stands at 451 feet tall.
There are actually 138 known pyramids in Egypt, most of which are smaller and less known. I will focus on the few which are more famous. It is also important to note that exact dates are impossible to give.
Archaeologists now tell us that the workers who built the pyramids were recruited from poor communities in Egypt, and worked in three-month shifts. There were 10,000 of them (considerably fewer than the 100,000 reported by Herodotus) and they ate relatively well.
The statue was carved from a single piece of limestone, and pigment residue suggests that the entire Great Sphinx was painted. According to some estimates, it would have taken about three years for 100 workers, using stone hammers and copper chisels, to finish the statue.
The construction of the pyramids is not specifically mentioned in the Bible. What we believe about their purpose does not impinge on any biblical doctrine.
They used levers to lift the capstone to a height of 20 feet (6.1 m). Four or five men were able to use levers on stones less than one ton to flip them over and transport them by rolling, but larger stones had to be towed.
