Why is a sphere not a polyhedron?
A sphere is not a polyhedron because it has no edges, no vertices and no flat faces The word 'polyhedron' means many faces.
How many faces does a polyhedron have with 18 edges and 12 vertices?
eight
How many faces vertices and edges does a pentahedron have?
In geometry, a pentahedron is a polyhedron with five faces. That can either be a square pyramid with 5 vertices, 8 edges and 5 faces or a triangular prism with 6 vertices, 9 edges and 5 faces.
How many faces edges vertices of tetrahedron?
Four faces, six edges and four vertices.
How many faces edges or vertices does a sphere have?
A sphere has no faces, no edges, and no vertices.
Why is a sphere not a polyhedron?
A sphere is not a polyhedron because it has no edges, no vertices and no flat faces The word 'polyhedron' means many faces.
If a polyhedron has 5 faces and 6 vertices how many edges are there?
It is a triangular prism that has 5 faces, 6 vertices and 9 edges
If a convex polyhedron has 12 edges and 8 faces then how many vertices does it have?
It has 6 vertices.
How many faces does a polyhedron have with 18 edges and 12 vertices?
eight
How many edges does a polyhedron have which has four faces and four vertices?
6
Polyhedron has 10 vertices and 10 edges how many faces?
Such a polyhedron cannot exist. According to the Euler characteristics, V + F - E = 2, where V = vertices, F = faces, E = edges. This would require that the polyhedron had only two faces.
There are 18 edges and 8 faces in a polyhedron. how many vertices does it have?
12 vertices A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A polyhedron with 22 faces and 60 edges has how many vertices?
v=60-20
How many faces and edges does a 3d polyhedron have?
The only thing that can be said that there must be at least 4 faces and at least 6 edges and that the polyhedron must satisfy the Euler criterion which requires that: Faces + Vertices = Edges + 2.
If a polyhedron has 10 more edges than vertices how many faces does it have?
Oh, dude, it's like a math riddle! So, if a polyhedron has 10 more edges than vertices, we can use Euler's formula: Faces + Vertices - Edges = 2. Since we know the relationship between edges and vertices, we can substitute that in and solve for faces. So, it would have 22 faces. Math can be fun... sometimes.
How many faces if there is 16 vertices and 37 edges?
If the object is a convex polyhedron, then, by Euler's characteristics, it should have 23 faces.
How many faces and vertices does a gemstone have with 22 edges?
The number of vertices and faces is 2 more than the number of Edges according to Euler's formula. So a gemstone with 22 edges must have a total of 24 faces and vertices.
