The roof of the classroom is composed of 6 equal isosceles triangles whose vertices meet in the center of the roof. If the inclined edges measure 20 feet and the height of the roof is 4 feet, what is the number of square feet of galvanized iron sheet necessary to cover the roof? (Disregard the waste in lapping, cutting, etc.)
