A triangular pyramid has a triangle-shaped base and all three triangular faces meet at the apex. There is a special case of a triangular pyramid called a tetrahedron, it has equilateral triangles for each of the faces. The triangular pyramid formula consists of both the volume and the surface...
Pyramids can be classified based upon the shape of their base. As already mentioned the base of a pyramid is a polygon, so if the base is a triangle then the pyramid is known as a triangular pyramid. Similarly if the base is a square then the pyramid is known as a square pyramid and...
triangular-based pyramid hexagonal pyramid There arean unlimited numberof 3d shapes. These are calledpolyhedrons, and their names are from the Greek word for the quantity (number) of faces (sides) on each shape. All faces are exactly the same as each other on regular polyhedrons; one or more...
