In order to construct the pyramids, the Egyptian needed to be proficient in engineering and

architecture. They had to accurately measure and layout the pyramid's base, as well as understand the principles of stability and structural integrity. Additionally, they needed advanced knowledge of mathematics to calculate angles, proportions, and dimensions. Expertise in quarrying and cutting stones was crucial in order to shape and transport the massive blocks used to build the pyramids. The Egyptians also developed innovative techniques to lift and position the heavy stones, such as using ramps, levers, and pulleys. Overall, the construction of the pyramids required a high level of technical expertise and practical skills in engineering and architecture.
