Because the solution is extruded directly into the precipitating liquid, this process for making fibers is called wet spinning. Acrylic, rayon, aramid, modacrylic and spandex can be produced by this process. Dry spinning is also used for fiber-forming substances in solution.
Menkaure's pyramid had an original height of 65.5 metres (215 feet) and was the smallest of the three major pyramids at the Giza Necropolis. It now stands at 61 m (204 ft) tall with a base of 108.5 m. Its angle of incline is approximately 51Â°20â²25â³. It was constructed of limestone and granite. The first sixteen courses of the exterior were made of red granite.
In reality, while Manetho ascribes Menkaure with a reign of 63 years, Egyptologists believe that he actually ruled for about 28 years (or at least, 26 years). That should have been long enough to built a much more substantial pyramid then his so-called Third Pyramid at Giza.
