Amazons new warehouse in North Haven, CT is using robots to pick the ordered goods from the shelfs and package them to be sent for the final destination. According to design requirements, one robot is supposed to handle 180 orders per hour. However, due to the complexity of order retrieval, robots have to travel long distances in the warehouse and are observed to handle 128 orders per hour. Furthermore, due to maintenance and battery charging requirements, each robot operates at 95% capacity efficiency, 365 days out of the year for 20 hours every day. How many robots will be needed to handle 10.8 million orders a year? PLEASE ROUND YOUR ANSWER UP TO THE NEAREST INTEGER.
