A dodecahedron is one of the Platonic Solids which has 12 pentagonal faces, 30 edges and 20 vertices
It is a cuboid that has 8 vertices, 12 edges and 6 faces
12, if you mean a dodecahedron, a 3-d figure with only pentagonal faces.
There is no simple way. You cannot go by the name - which can refer to the number of faces. You can have different shapes with the same number of faces. The following are all examples of a hexahedron (six faces): triangular dipyramid (9 edges), pentagonal prism (10 edges), rectangular prism (12 edges). One contributor has suggested it might be easier to count the faces and vertices (corners). Add the two numbers and then subtract 2. *This will work if the shape has been simplified as much as it can be. The 2 is only valid if there are no holes in the shape. For example, a pentagonal prism: 6 faces, 6 vertices. Sum = 12. Subtract 2 = 10. A pentagonal pyramid has 10 edges.
A hexagonal prism

A dodecahedron has 12 equilateral pentagonal faces. From this, it has 30 edges as well as 20 vertices in its shape.
It has 12 pentagonal faces and 12 vertices.
Heptagonal prism * * * * * No, a heptagonal prism has 9 faces. The correct answer is a hexagonal pyramid.
A Dodecahedron has 12 pentagonal faces.
Faces= 2 edges=5 vertices=12 Faces= 2 edges=5 vertices=12
Number of faces= 7 Number of sides= 12 Number of vertices= 1
A 3D 5 sided shape is called a dodecahedron. It is a solid with 20 vertices, 30 edges and 12 equal pentagonal triangular faces.

A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.
A dodecahedron is a 3-dimensional shape with 12 (dodeca-) polygonal faces. There are more than 6 million different types of convex dodecahedra. For example, a hendecagon based (11-sided polygon) pyramid, which has 12 vertices;a decagon based prism, which has 20 vertices;a hexagon based dipyramid which has 8 vertices.Then there is the regular Platonic solid, made out of 12 regular pentagonal faces. This has 20 vertices.
It is a solid shape with six faces. There are seven topologically distinct convex shapes and three concave ones. The faces can be triangles, quadrilaterals or pentagonal and the number of edges can range from 9 to 12. The number of vertices is 4 fewer than the number of edges.
