A department plans to file 1,000 records, with each record 1 inch thick, using six-shelf open filing units where each shelf is 33 inches long. How many filing units should be purchased?
Correct Answer:
6
Explanation:
When planning filing space, you compare the total thickness of the records to the capacity of each storage unit. A single shelf is 33 inches long, and each record is 1 inch thick, so you can fit 33 records on one shelf. A unit has six shelves, so it can hold 6 × 33 = 198 records. To store 1,000 records, you need 1,000 ÷ 198 ≈ 5.05 units, which means you must round up to 6 units. Five units would hold 5 × 198 = 990 records, which is not enough. Therefore, six filing units should be purchased.
