a triangular based pyramid
the answer is tetrahedron
A shape with exactly four identical faces is a tetrahedron. A regular tetrahedron has four equilateral triangular faces, all of which are congruent. Each face meets the others at a vertex, resulting in a three-dimensional figure with four vertices and six edges. This geometric shape is one of the simplest forms in three-dimensional space.
The only pyramid with exactly four faces is the triangular pyramid.
There is no such shape. The only convex shape that has four faces is a tetrahedron, and that has four vertices, not 5.
A tetrahedron.
There is no solid shape with exactly four squares and no other faces.

A shape with exactly four identical faces is a tetrahedron. A regular tetrahedron has four equilateral triangular faces, all of which are congruent. Each face meets the others at a vertex, resulting in a three-dimensional figure with four vertices and six edges. This geometric shape is one of the simplest forms in three-dimensional space.
No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
The only pyramid with exactly four faces is the triangular pyramid.
A cube has 6 faces
There are an infinite no of shapes that have exactly 4 triangular faces. The two commonest are a tetrahedron and an Egyptian pyramid. If the question is re-phrased to "What shape has exactly four faces, (all of which are triangular), then the only answer is a tetrahedron. An Egyptian pyramid has five faces - a square base and four triangular sides. It is regular (the apex is vertically above the center of the base) and the sides are isosceles.
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
There is no such shape. The only convex shape that has four faces is a tetrahedron, and that has four vertices, not 5.
A three-dimensional figure or shape, such as a tetrahedron, has four faces. These faces are equilateral triangles. A tetrahedron also has four vertices and 6 edges.
Pyramid - they have three sides and a base = four faces
