How big is it? The Great Pyramid's foundation is square, with each side measuring **230 meters** (756 feet) and occupying an area of **5.3 hectares** (13 acres). It is the largest single block of stone on Earth.

The pyramid itself is larger than what you might think at first glance- the base of the structure covers an area of about 32,000 m2 (351,000 ft2). In **other words**, it's pretty much a huge square!

Here's how Robert M. Schoch Jr., a professor of physical science at Boston University who has studied ancient architecture extensively, describes the Great Pyramid: "As impressive as this monument [the Great Pyramid] is, one should not overlook its simplicity and elegance. The Egyptians seemed to have had no need for complicated engineering designs to construct such magnificent buildings."

Schoch also notes that the quality of construction of **the Great Pyramid** has been debated since it was first identified in Giza in 1772. Some early scholars believed it to be a fake created by the French or others looking for money, but this theory has now been largely discredited.

In fact, recent studies have shown that the original design and construction of the pyramid could only have been accomplished through using **extremely advanced technology** available in Egypt at the time.

Significant citation The Great Pyramid is the biggest of the three, with an average length of each side at the base of 755.75 feet (230 metres) and an initial height of 481.4 feet (147 metres). It is also the oldest, dating back to 2560 BC. The second largest pyramid is Khafre's at 513.52 feet (157 metres), and it was built for about 20 years later than King Khufu's pyramid. As for Menkaure's, its exact size is not known because its rubble has been used as filler in other pyramids but it probably wasn't very large.

The Great Pyramid of Giza was originally called the Pyramid of Cheops after **its builder**, Cheops (pronounced kheops). It was later named after King Khufu, who ordered the building of the pyramid. In fact, only one king is directly associated with the pyramid: Khufu. However, many other Pharaohs may have commanded the project to be done or given permission to use the stones left over after **its completion**, thus making them co-conspirators in the crime of **pyramid building**.

There are several reasons why the Great Pyramid of Giza is so significant in history and anthropology. First of all, it is the highest structure on earth up until this date.

The height of **this pyramid** is 341 feet (104 meters). Each side of the foundation is 722 feet long (220 meters). This is only little less than the height of Giza's Great Pyramid. Pharaoh Sneferu erected this pyramid (Old Kingdom). From **around 2613 BC** until **2589 BC**, he ruled Egypt.

The pyramid was built as a tomb for himself and his wife. It would have been the greatest monument of its time and probably beyond. But it is believed that he might have been killed before finishing it.

Who built the Great Pyramid at Giza? The Great Pyramid of Giza is the oldest and one of the biggest pyramids in the world. It is located near Cairo, Egypt, and stands 467 feet (140 meters) high. The pyramid was built during the Fourth Dynasty (2613-2500 BC). Its builder has never been identified with certainty but likely was one of the Egyptian pharaohs of the fourth dynasty. Some believe the pyramid may have been built by Thutmose IV, who reigned from 1479 to 1450 BC. Others think it could be Khufu (also called Chephren), who reigned from 2589 to 2566 BC. Still others suggest that it may have been Mycerinus, who reigned from 2903 to 2861 BC, or even Menkaura, who reigned from 2437 to 2394 BC.

The pyramid is 116 feet broad and 70 feet tall at its base. 95 tons of steel and 105 tons of aluminum support the framework. Three lesser pyramids flank the main pyramid. They were placed to generate light shafts allowing access to the museum's collections. The overall size of the site is 5 acres.

The Louvre was built between 1753 and 1791 by French architect Louis Le Vau. He modeled the building on **Egyptian monuments** and intended for it to serve as a royal palace and museum. The building consists of two symmetrical parts, an upper house-like gallery and a lower block with offices, storage rooms, and workshops. The central part of the lower floor is occupied by the sculpture gallery. It contains some of the most famous works of art in the world: Michelangelo's _David_, Canova's _Venus_, Bernini's _Apollo and Daphne_, Rodin's _The Thinker_, and more.

In 1883 Emperor Napoleon III decided to have his own pyramid constructed within the grounds of the Louvre to accommodate more art. The design was chosen by **Gabriel Montford** who also designed New York's Guggenheim Museum. It is 71 feet high and 55 feet wide based on a core of American cedar trees that were grown specifically for this purpose. Above the core is a flat platform that covers the entire top area of **the main pyramid**.

The pyramid is therefore 400 cubits per side by 280 high in ancient Egyptian measurement. Mathematically, there is a link between the length of the base and the height of **one side**: 1.25, a ratio that the makers, of course, have perfected. The Great Pyramid is therefore about 470 feet (145 m) on each side.

In modern measurement systems, the base of the pyramid is 0.9 miles (1.4 km) across, and the height of its most elevated point is 409 feet (125 m).

What is the volume of a pyramid? A pyramid has a constant width from bottom to top, which means that it can be modeled as a cylinder. Volumes of cylinders are given by the formula $V = \frac{lw}{3}$, where l is the height of the cylinder and w is the width. In this case, l equals 409 feet (125 m) and w equals 2 feet (60 cm). Therefore, the volume of the pyramid is 4091 cubic feet (115 m3), not counting the roof which would add **more space**.

What is the weight of the Great Pyramid? According to some sources, the weight of the pyramid itself is 2.6 million pounds (1116 kg). This means that if someone were to pick it up and put it down again, it would collapse due to its own weight.
