It could be a deltahedron. A deltahedron has all faces being an equilateral triangle. The amount of faces can vary from 4, 6, 8, 10, 12, 14, 16 and 20.
Answer:
50Hz x .10m = 5 m/s
20 m/s divided by .50m = 40Hz
80 m/s divided by .20m = 400Hz
120 m/s divided by .40m = 300Hz
340 m/s divided by 440Hz = .77m
you add 78 plus 37 then subtract from 180
