2998 feet of glass was needed to cover the pyramid. You add 646 plus 350 and multiply by 3, which is the side length of the pyramid. (Pyramids or triangles have 3 sides.)
The area of the entire sector of DEF = 60 / 360 * PI * radius^2
sector area = 1 / 6 * 3.14159265... * 20^2
sector area =

segment area = sector area - triangle DEF Area
triangle DEF Area = (1/2) * 20 * sine 60 * 20
triangle DEF Area = (1/2) * 0.86603 * 400
triangle DEF Area = <span><span><span>(1/2) * 346.412
