Storage space of a warehouse must be allocated to two products. Product 1 has 100 orders a day. Average inventory is 10,000 units, and each unit takes 2 cu ft of storage space. Product 2 has 50 orders a day. Average inventory is 4,000 units, and each unit takes 4 cu ft of storage space. Calculate COI of both products. Which product should be stored closer to shipping dock?
