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
The shape of a triangular based pyramid has 4 vertices, 6 edges and 4 faces
A triangular based pyramid has 4 faces, 6 edges and 4 vertices
It is a triangular prism that has 6 vertices, 9 edges and 5 faces.
It is a pentagonal based pyramid that has 6 vertices, 6 faces and 10 edges
That 3D shape is called triangular pyramid.
tetrahedron
Pentagonal Pyramid
It is a cuboid
Triangular prism
the triangular pyramid
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
There is no simply connected 3-d shape because it is not consistent with the Euler characteristic.
