5 edges, 5 verts, and faces are only on 3d shapes, for the most part, so any 2d shape has 1
8 edges and 5 faces
According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
There are infinitely many shapes that do.
A cube has 6 faces

A cylinder and a cone - are two entirely different 3D shapes. A cylinder has three faces & two edges. A cone has two faces and one edge.
6 faces, 12 edges
8 edges and 5 faces
There is no 3d shape made up of octagons. An octahedron can be one of several different shapes - but without ANY octagonal faces. For example, A hexagonal pyramid (8 faces, 18 edges, 12 vertices) A heptagonal pyramid (8 faces, 14 edges, 8 vertices) A quadrilateral dipyramid (8 faces, 12 edges, 6 vertices)
According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
3D shapes that only have flat faces are known as polyhedra. Examples include cubes, tetrahedrons, and octahedrons. Each of these shapes is composed entirely of flat polygonal faces, edges, and vertices. In contrast, shapes like spheres or cylinders have curved surfaces and do not fit this category.
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
