  1. It took 20 years to construct the great pyramid of Khufu at Gizeh in Egypt. This pyramid is 500 feet high and has a square base with edge length 750 feet. Suppose also that the pyramid is made of rock with density ρ = 120 lb/cubic foot. Finally suppose that each laborer did 160 ft/lb/hour of work in lifting rocks from ground level to their final position in the pyramid and worked 12 hours daily for 330 day/year. How many laborers would have been required to construct the pyramid? I have attached my work here. Thanks for helping.
