PRINTER VERSION BACK NEXT Chapter 01, Problem 034 Two types of barrel units were in use in the 1920s in the United States. The apple barrel had a legally set volume of 7056 cubic inches; the cranberry barrel, 5826 cubic inches. If a merchant sells 68 cranberry barrels of goods to a customer who thinks he is receiving apple barrels, what is the discrepancy in the shipment volume in liters (L)? Give your answer as a positive number Number 83640...
