# of faces + # of edges + # of vertecies + 2
Sphere
It has 6 faces, 12 edges and 8 corners or 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.
sphere
A solid cone has 2 faces and 1 edge
Sphere ( 0 faces , 0 edges , 0 vertices )
retangle
# of faces + # of edges + # of vertecies + 2
Faces= 2 edges=5 vertices=12 Faces= 2 edges=5 vertices=12
A cube has 6 faces
a cuboid has 6 faces, 12 edges and 8 vertices this is a 3d cuboid incase you get mixed up
Sphere
It is a square based pyramid that has 5 faces, 8 edges and 5 vertices
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)
It has 6 faces, 12 edges and 8 corners or vertices
Well, honey, that sounds like a hexagonal prism to me. It's got those six faces, six vertices, and ten edges, making it the life of the 3D shape party. So, go ahead and strut your stuff with that hexagonal prism knowledge!
