Can # 3 had 1.5 inches of piddle . Can # 4 had 0.5 inches of body of water . Can # 5 had 0.5 inches of body of water . Added together ( 1.5 + 1 + 1.5 + 0.5 + 0.5 ) , that equaled 5 column inch of body of water . Divide that by five because there were five cans ( 5 inches/5 cans ) so that ’s 1 in on average .
