A zoo is building an aviary (an enclosure for birds) with a rectangular footprint to house hoopoes because they are strange looking. The aviary will be 20 feet tall, and has one side that is twice as long as the other. There will also be a viewing space in the middle and a walkway to it that takes 4800 cubic feet in total. Each bird needs at least 1500 cubic feet to prevent overcrowding. If the zoo wants
to have 40 of these birds, how big will they need to build the aviary?
