The ancient Egyptians had the ability to complete sophisticated engineering projects, such as massive pyramids and huge temples, using primitive tools. They have developed stone-cutting methods and transported large rock masses, placing them neatly in their designated places of construction. The pyramids were built on a perfectly flat base; Builders, engineers and construction workers used parts of their bodies as a measurement system for length. The primary unit of measurement was the arm, the distance from the elbow to the top of the middle finger of the palm. Despite variations in size for body parts for different workers, that system was appropriate for small enterprises. The royal arm, length 5, 52 cm (6, 20 inches) was used as a criterion in the construction of temples and pyramids; it required greater precision.
