1. Egyptian pyramids are great monument of a great civilization that was born seven thousand years ago. The ancient Egyptians built more than 90 royal pyramids, from about 2630 BC until about 1530 BC. During that time, the pyramid shape evolved from a series of stepped terraces to sloped pyramidal shape.
2. The first pyramid, the Step Pyramid at Saqqara, was constructed during the reign of King Djoser (Zoser) (2630 BC-2611 BC). The largest pyramid in Egypt is the one built for King Khufu, in Giza. Khufu’s pyramid, known as the Great Pyramid, is the only one of the Seven Wonders of the World that still exists.
3. Egyptian pyramids were originally built to serve as tombs for kings and queens. After a ruler died, his or her body was carefully treated and wrapped to preserve it as a mummy. According to ancient Egyptian belief, the pyramid, where the mummy was placed, provided a place for the king to pass into the afterlife.
4. There are many theories of how the pyramids were built but no body knows for sure the process ancient Egyptians followed to build the pyramids. One theory suggests that ramps were built to drag the blocks of building stones on sledges to the top. There are some evidence that this theory might be close to the truth as some parts of the mentioned ramps were found near building sites. These ramps were made of bricks and earth rubble and they were strong enough to carry the huge blocks used to build the pyramids.
5. Stones used in the construction process were quarried from remote or local quarries where they were either transported using wooden sleds as the wheel had not yet existed and even it had it wouldn't be of much use due to the heavy weight of the blocks.

Editor's Notes
A sloping surface, such as a ramp. An inclined plane can be used to alter the effort and distance involved in doing work, such as lifting loads. The trade-off is that an object must be moved a longer distance than if it was lifted straight up, but less force is needed. You can use this machine to move an object to a lower or higher place. Inclined planes make the work of moving things easier. You would need less energy and force to move objects with an inclined plane.
