Solution: Given, the length of the wire = 60 ft. We know that an octahedron has 12 edges. Hence, the length of each edge of the octahedron = 60/12 = 5 ft. Therefore, Length of each edge of the octahedron = 5 ft Practice Questions on Octahedron FAQs on Octahedron Is Octahedron a Prism? sian walton pics
