A pentagonal pyramid
A pentagonal pyramid (5 sides and 1 base) has 6 faces, 6 vertices, and 10 edges (5 between the sides and 5 with the base).
A sphere has no corners and no edges
A pentagonal pyramid has 10 edges.
It is a pentagonal based pyramid that has 6 vertices, 6 faces and 10 edges
it is a decagon
A pentagonal prism has 7 faces, 15 edges and 10 vertices
A heptagonal prism gas 21 edges.
It is a pentagonal based pyramid that has 6 vertices, 6 faces and 10 edges
the edges of a shape are basicly the sides of a shape
A pentagonal prism.
If it's a pyramid, it has 10 edges.
The 3D shape that has 6 vertices, 6 faces, and 10 edges is a hexagonal prism. A hexagonal prism is a polyhedron with two hexagonal faces and six rectangular faces connecting them. It has 6 vertices where the edges meet, 6 faces (2 hexagonal and 4 rectangular), and 10 edges that form the boundaries between the faces.
There is no simply connected 3-dimensional shape that meets these requirements.
