Let us start here: 1. Otley Beyer, an American anthropologist who moved to Ifugao in 1905 and spent the rest of his life studying the culture and history of the Banaue Rice Terraces, stated that the 8th wonder of the world was built for more or less a thousand years by indigenous people largely by their hands with the aid of minimal primitive tools. The terraces-which resemble steps carved into the mountainside-cover some 10,360 square km (Tikkanen, 2017). Assuming that each year for 1000 years, the same number of people work equally to finish the terraces, and each laborer worked 1 hectare (10000sq. m) in total, 8 hrs a day in 365 days or 1 year. Also, if a total of 1.2 1x10°kWh of Work were done by all the laborers, what is the average power of each worker? Cliven: Total Work done - no of working hours/worker - Bhrs 365 - Area worked/laborer - 10,000 sq m. Total Area (in sqm.) - 10360 * 1 x109 sqm Total No. of workers or laborer= (total Area)/ ("10000sq m.) No of workers each year = total no. of workers /1000 yrs Required: formula: Execute: Work done per worker - Total work done/Total no. of workers Average power - Work done per worker/ no of working hours per worker
