A square and a rectangle as well as other quadrilaterals
If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
A sphere- there are no faces, edges or vertices
It has 7 faces, 15 edges and 10 vertices
Faces + Vertices = Edges + 2
The REGULAR dodecahedron, formed from 15 pentagonal faces, has 30 edges. But there are a number of other 3-dimensional figures which have 12 faces (sides), with different numbers of edges and vertices.
Sphere ( 0 faces , 0 edges , 0 vertices )
There is not a polyhedron with the given number of faces, edges and vertices.
a hexagonal pyramid
A cuboid or a cube has 12 edges, 6 faces and 8 vertices
A cube and a regular octahedron have the same number of edges, vertices, and faces. Both have 12 edges, 8 vertices, and 6 faces.
for any prism , number of ___ + number of vertices = number of edges + ___
The solid figure that has the same number of faces and vertices and has 8 edges is a cube. A cube has 6 faces, 8 vertices, and 12 edges, so it fits the description given.
