Jay's Barbecue™ wanted to add soup to his menu. His food suppliers said that there was only 1 deal he could get. It was as many boxes of 22 inches long by 15 inches wide by 24 inches tall boxes he wanted with cans of soup that had 3-inch diameters and 4.5-inch tall cans each box. If Jay wants about 1,500 cans of soup how many boxes will he need to purchase?
