Faces= +1 Eges= *2 Vertieces= +1 to the shape of the prism
A pyramid does.
A square based pyramid would fit the given description.
A cone has 1 face, 0 edges, and one vertex. The face is the circular flat area. The cone can roll, so it has no edges. Edges have to be straight. The vertex is the pointy thing opposite to the face.
the formula is (vertices+faces)- 2= edges
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 4 vertices
if you add 1 to 9 it gives you 10 so then take the edges away from that and you will get 6 edges for the faces 10 -4faces witch is 6 then 6vertcies -10 edges ferom the begining wi8ch is-23 i think loo its all wrong i was loling
Faces + Vertices = Edges + 2 This is called Euler's formula. For example a cube has 8 vertices, 6 faces and 12 edges so: 6 + 8 = 12 + 2 14 = 14 The formula works.
Euler
In a prism, the number of faces, vertices, and edges are related by the formula F + V - E = 2, known as Euler's formula. For a prism, which has two parallel and congruent faces connected by rectangular faces, the number of faces (F) is equal to the sum of the number of rectangular faces and the two congruent bases. The number of vertices (V) is equal to the number of corners where edges meet, and the number of edges (E) is equal to the sum of the edges around the bases and the edges connecting the corresponding vertices of the bases.
The formula for hexagonal prism is ,it has 8 faces,it has 12 verities and 18 edges
By Euler's formula the number of faces (F), vertices (V), and edges (E) of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.
Faces + Vertices= Edges + 2 F+V=E+2 For a polyhedron, count up all the faces, vertices, and edges and substitute in formula. If both sides of the equation aren't equal, Euler's formula is not verified for the polyhedron.
