According to InfoPlease.com, Iowa has a land area of 55,869.36 square miles, and a total (land and water) area of 56,271.55. According to Google, the conversion rate is 640 acres per square mile, so (if my calculator is working) that's 35,756,390.4 acres of land and 36,013,792 acres total. --Erin Kiley
