A dodecagon is a two-dimensional shape and so has only one face.
A triangle has three faces. In geometry, a face refers to a flat surface of a solid shape. Since a triangle is a two-dimensional shape with three sides, it has three faces. Each side of the triangle forms one of its three faces.
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
A shape that has 6 congruent faces is known as a cube. A cube is a three-dimensional shape with 6 square faces, where each face is identical in size and shape. The cube is a regular polyhedron, meaning all its faces are congruent regular polygons and all its angles are equal.
Lateral Face - In a prism, the faces that are not bases. In a pyramid, faces that intersect at the vertex.
