Mr. Kelly is a dairy farmer at heart. He has a huge red barn in his yard that holds hay for all his cows. Mr. Kelly was “bragging” that he could put hay in the barn in November and feed his cows for a whole year. Mr. Brust who fancies himself a bit of a know-it-all tells him that is impossible. Brust “claims” that dairy cows need 150 feet3 of hay a year and that the barn won’t contain enough hay for Mr. Kelly’s 215 cows. The height of the side walls on his barn are 20 feet, its 40 feet long, 30 feet wide and from the vertex of the roof its 35 feet tall. Who is right? How many cows could Mr. Kelly’s barn feed for one year?
