Mathematical facts about Giza pyramids

The Giza pyramids, located in Egypt, are some of the most well-known and studied pyramids in the world. Here are a few mathematical facts about the Giza pyramids:

1. The Great Pyramid of Giza, also known as the Pyramid of Khufu, is the largest of the Giza pyramids and is considered one of the Seven Wonders of the Ancient World. Its base covers an area of 13.1 acres and it is estimated to have contained around 2.3 million limestone blocks.
2. The Great Pyramid is also known for its precision in construction. Its base is level to within 15 cm (6 inches) and the sides are oriented to the four cardinal points with an accuracy of 3/60th of a degree.
3. The pyramid’s slope angle is 51.5 degrees, which is the most efficient angle to build a pyramid of that size.
4. The ratio of the pyramid’s height to half its base length is close to the mathematical constant pi (π), which is approximately 3.14.
5. The pyramid’s perimeter is about 984 meters (3,228 ft) and its original height was 146.5 meters (481 ft).
