pentagon
A cuboid can have 6 rectangular faces, 12 edges and 8 vertices
Not too sure but you may be thinking of a cube which has 6 same flat faces, 12 edges and 8 vertices
L-Shaped Prism & Hexagonal Pyramid
A triangular based pyramid has 4 faces, 6 edges and 4 vertices
what polygon has 6 edges 4 vertices and all faces meet at vertex
It is a triangular prism that has 6 vertices, 9 edges and 5 faces.
That 3D shape is called triangular pyramid.
tetrahedron
Pentagonal Pyramid
the triangular pyramid
Triangular prism
It is a cuboid
A Triangular based Pyramid has 4 vertices, 6 edges and 4 faces.
i would say a cube
A cuboid can have 6 rectangular faces, 12 edges and 8 vertices
Well, honey, that sounds like a hexagonal prism to me. It's got those six faces, six vertices, and ten edges, making it the life of the 3D shape party. So, go ahead and strut your stuff with that hexagonal prism knowledge!
There is no simply connected 3-d shape because it is not consistent with the Euler characteristic.
