A bale of hay is a rectangular solid weighing approximately 80 pounds. It has a length of 36 inches, a width of 18 inches, and a height of 5 inches. (The volume V of a rectangular solid is given by V = length · width · height.) Approximate the number of bales in a ton of hay. Then approximate the volume of a stack of baled hay in cubic feet that weighs 12 tons. (2000 lb = 1 ton)
