# How did the Egyptian engineers of the Third and Fourth Dynasty construct the Pyramids and Sphinx without modern science and mathematics?

## How did the Egyptians construct the Great Sphinx?

The Sphinx was not assembled piece by piece but was carved from a single mass of limestone exposed when workers dug a horseshoe-shaped quarry in the Giza plateau. Approximately 66 feet tall and 240 feet long, it is one of the largest and oldest monolithic statues in the world.

## How did Egyptians build pyramids with math?

They used simple math to make such a great pyramid. They used the Pythagorean Theorem, trigonometry and simple algebra. They also measured the angle of each direction so that each side of the pyramid was facing exactly north, south, east and west.

## How did the building of the pyramids contribute to math?

The Egyptians employed the equivalent of similar triangles to measure distances. For instance, the seked of a pyramid is stated as the number of palms in the horizontal corresponding to a rise of one cubit (seven palms).

## How do modern historians of Engineers think the pyramids were built?

Most modern scholars think they were built with ramps: the crumbling stone chips from the Mokattam formation quarries were close by and may well have provided the secondary material for the ramps. “This was one of the many insights given us by the geologists,” Lehner says.

## How was the Great Sphinx built and why?

The giant statue of the Great Sphinx was built more than 4,500 years ago, to guard the pyramid of Khafre at Giza. It has the head of a pharaoh and the body of a lion. The Great Sphinx was carved out of a huge outcrop of limestone that sticks up above the desert floor.

## How did they build the pyramids?

The most plausible one is that the Egyptians employed a sloping and encircling embankment of brick, earth, and sand, which was increased in height and length as the pyramid rose; stone blocks were hauled up the ramp by means of sledges, rollers, and levers.

## How do we know that ancient Egyptians could think scientifically and mathematically?

The ancient Egyptians were the first civilization to develop and solve second-degree (quadratic) equations. This information is found in the Berlin Papyrus fragment. Additionally, the Egyptians solve first-degree algebraic equations found in Rhind Mathematical Papyrus.

## How did Egyptians use math and science?

They devised a system of weights to help in the sale of products. Angles of pyramids and volume of columns were calculated with great accuracy. In addition, they knew how to calculate the area of squares, rectangles, and circles. Just as we do, ancient Egyptians divided circles into three hundred and sixty degrees.

## How mathematically perfect are the pyramids?

He notes that the Great Pyramid is nearly perfectly aligned along the cardinal points—north, south, east and west—with “an accuracy of better than four minutes of arc, or one-fifteenth of one degree.”

## How was the Sphinx Temple built?

The Sphinx Temple was built with limestone blocks carved in the rock of the Giza Plateau, in local quarries.

## How was the Greek Sphinx created?

In Greek mythology, the Sphinx was a monster. Some accounts note that it had the body and tail of a lion, the face of a woman, and the wings of a bird. It was an offspring of Echidna and Typhon, who also bore such other monsters as the Hydra, the Chimera, the many-headed dog Orthus, and the nasty Gorgons.

## Who actually did the construction of the Sphinx?

Most scholars date the Great Sphinx to the 4th dynasty and affix ownership to Khafre. However, some believe that it was built by Khafre’s older brother Redjedef (Djedefre) to commemorate their father, Khufu, whose pyramid at Giza is known as the Great Pyramid.
