The shape you are describing is a tetrahedron. A tetrahedron is a type of polyhedron that has four triangular faces, six edges, and four vertices. It is the simplest three-dimensional shape in geometry and is a fundamental building block in various fields such as chemistry and architecture.
Sphere
There is no such 3-d shape if it also has flat faces.
Not too sure but you may be thinking of a cube which has 6 same flat faces, 12 edges and 8 vertices
It is a cuboid or a cube
A face of a polyhedron is one of the flat surfaces. These are two dimensional objects. Two faces meet at an edge, which is a line - a one dimensional object. Three or more edges meet at a vertex which is a point. A point has no dimensions.

The shape you are describing is a triangular prism. It has six vertices, nine edges, and five flat faces (two triangular faces and three rectangular faces). Additionally, it has no curved surfaces, as all its faces are flat.
The shape with 8 vertices, 12 edges, and 6 flat faces is an octahedron. It is a type of polyhedron that is characterized by having eight triangular faces. Each vertex of the octahedron is formed where four edges meet, and it is one of the five Platonic solids.
The 3D shape with 12 edges is a dodecahedron. It is a polyhedron with 12 flat faces, each of which is a regular pentagon. When laid out flat, the dodecahedron can be represented as a net, which shows how the faces connect to form the three-dimensional shape.
i think it might be a circle but im not sure
triangula prism
The shape you are describing is a cylinder. A cylinder has two flat circular faces (the top and bottom) and one curved surface that wraps around the sides. It has no edges or vertices where flat surfaces meet, as the curved surface is continuous.
