Isn't the Great Pyramid of Giza's foundation square? No, not exactly. Contrary to popular belief, the Great Pyramid is an eight-sided building, not a four-sided construction. From base to tip, each of the pyramid's four sides is evenly separated by extremely tiny concave indentations. These holes are called "bastions" and they contain the remains of pharaohs who were buried with them.

In order for the pyramid to be a true octagon, **each side** would have to be about 755 feet long (227 meters), which is almost half a mile. The average size of a pyramid found in Egypt today is around 50 feet (15 m) on each side, so it can be assumed that the Great Pyramid is about 150 feet (45 m) longer than it is wide.

The Great Pyramid was built as a tomb for King Khufu, who reigned from 2589 to 2566 B.C. He had two other brothers who also ruled over small parts of Egypt at different times, but they are not considered great leaders because they did not build anything. When King Khufu died, he was buried inside his pyramid along with many treasures belonging to him and his family. His wife and children were given proper burials too. This shows that royalty was not always treated badly during ancient times; sometimes they even got good care. Today, only parts of the original structure remain because over the years wind and water have taken their toll.

A pyramid's base can be a triangle, a square, a rectangle, or any form with more sides. A triangle is formed by each side of a pyramid (the base edge and the apex). The Egyptian pyramids may have been inspired by a holy, pointed stone known as the ben-ben. This too is made up of three parts: a triangular head, a flat surface, and a sharp point.

The shapes of **Egyptian pyramids** reflect **their purpose** which was to provide a platform for the burial of the pharaoh. The more sides a base has, the more space it provides for the placement of large stones used to stabilize the pyramid. There are only four regular polygonal numbers below ten: 3, 4, 6, and 9. Therefore, the bases of Egyptian pyramids usually consist of squares, rectangles, or triangles with those numbers of edges.

Pyramids were built over a very long period of time using thousands of workers. It would not have been possible for them to know **the exact shape** that the base of the pyramid should have before they started building it. When archaeologists study the ruins of ancient buildings, they often find pieces of broken tools such as axes, saws, and chisels among the rubble. These tools break when thrown down from high places like the tops of pyramids. Because of this, we can assume that the first builders of the pyramids probably had no choice but to start building our with what materials were available.

The Giza Great Pyramid is one of the most famous pyramids in the world. It was built as a tomb for the pharaoh Khufu and is therefore also known as "the king's pyramid". The pyramid is based on a central core of **stone beams** (mastabas) that form a square plan with **four sides** about 48 meters long and about 23 meters high. The apex of the pyramid is about 100 meters above sea level.

There are three main theories about who constructed the Great Pyramid: Egyptians, foreigners, or a team of people working together. Current evidence supports the theory that Egyptians were responsible for building the pyramid.

In addition to being a great monument of architecture, the Great Pyramid at Giza is also important for modern scientists because it contains some of their best preserved bodies ever found. In fact, the mummies inside the pyramid are so well preserved that they continue to provide information about ancient Egyptian life today. For example, scientists have used the patterns of hair and skin on some of the corpses to recreate pictures that show what people looked like in life and in death.

If a pyramid has a square base, it is referred to as a "square pyramid." If a pyramid has a rectangular base, it is referred to as a "rectangular pyramid." It's an interesting fact that all square pyramids may also be termed rectangle pyramids, but not the other way around. A square pyramid can be constructed by using a square as its base, while a rectangular pyramid requires a rectangle as its base.

There are many different kinds of pyramids, but these are the only two that have bases that are either square or rectangular, respectively.

A square pyramid has a square base, and a rectangular pyramid has a rectangular base. There are other kinds of pyramids as well, such as triangular, hexagonal, and octagonal. These other types of pyramids have bases that are not only non-equal, but may also be irrational numbers. For example, the Great Pyramid of Giza has a base made up of 9981/100 feet (3348.5 m), which is approximately 1/50th of a mile (0.16 km). This makes it the largest known pyramid in the world.

Some authors include the D'Nealian within **their definition** of **a rectangular pyramid** because it has dimensions that are proportional to those of a rectangle. However, this type of pyramid has a base that is not equal to the height, so it does not satisfy the definition of **a true pyramid**.
