That object would be called a triangular pyramid, also known as a tetrahedron.
The 3D shape you are describing is a pentagonal pyramid. It has a pentagonal base with five sides, and five vertices where the triangular faces meet. The three rectangle faces are lateral faces that connect the triangular base to the apex of the pyramid. The pentagonal pyramid is a type of pyramid with a polygonal base and triangular faces.
A three dimensional triangular figure with three faces and a base is called a triangular pyramid. It has four vertices, four faces, and six edges.
The given description fits that of a triangular based pyramid which has 4 faces, 6 edges and 4 vertices

False. A rectangular pyramid has a rectangular base and four triangular faces that converge at a single apex. Therefore, it cannot have only three triangular faces; it must always have four.
A tetrahedron.
A triangular prism has two triangular bases and three lateral rectangular faces. It has five faces in all so that it is a pentahedron.A triangular pyramid has a triangular base and three triangular lateral faces. It has 4 faces in all so that it is a tetrahedron.
A polyhedron that has a face that is not a base is a triangular prism. In a triangular prism, the two triangular faces serve as the bases, while the three rectangular faces are considered lateral faces. These lateral faces are not bases, demonstrating that a polyhedron can have faces that are not classified as bases.
It is a 3D shape comprising a triangular base and three triangular lateral faces rising from its edges to meet at an apex above the base.
A three-dimensional shape with one square base and four triangular lateral faces is called a square pyramid. The square base serves as the foundation, while the triangular faces converge at a single point, known as the apex, above the base. This geometric structure is commonly found in architecture and various designs.
A pyramid.
Yes, three-dimensional figures can have lateral faces that are rectangles, specifically in the case of rectangular prisms and pyramids. A rectangular prism consists entirely of rectangular faces, including its lateral faces. In contrast, a rectangular pyramid has a rectangular base and triangular lateral faces, although it can be visualized with rectangular lateral sections if divided appropriately. Thus, while prisms have all rectangular lateral faces, pyramids typically feature triangular lateral faces.
The 3D shape you are describing is a pentagonal pyramid. It has a pentagonal base with five sides, and five vertices where the triangular faces meet. The three rectangle faces are lateral faces that connect the triangular base to the apex of the pyramid. The pentagonal pyramid is a type of pyramid with a polygonal base and triangular faces.
A pyramid
It is a pentahedron with a rectangular base and four triangular lateral faces.
The description given could fit that of a pyramid
3. You wanna know how?? First there are 3 triangles that touch the base, so there are only 3 lateral faces. :)
