WebJun 17, 2024 · The truncated cube is a 3D uniform polyhedron bounded by 14 polygons (8 triangles and 6 octagons), 36 edges, and 24 vertices. It may be constructed by truncating the cube's vertices at (2-√2) of its edge length. More simply, it may be constructed by radially expanding the cube's edges outwards by 1/√2 of its edge length and taking the convex hull. rawlings 1175 heart of the hide
