One
triangular pyramind has four sides.
Bases and faces are the same, so a triangular prism will have 6 faces/bases.
it depends on the the kind of shape it is.
It has one base.
4
3 sides 1 base
A prism has 2 bases and a pyramid has 5 faces
A rectangular pyramid has 5 bases. The base of a pyramid is the polygon upon which the pyramid stands, and in the case of a rectangular pyramid, there are four triangular faces that meet at a single rectangular base. So, the total number of bases in a rectangular pyramid is 1 (rectangular base) + 4 (triangular faces) = 5 bases.
Any one of the four triangular faces.
A triangular based pyramid (which is a tetrahedron) has 1 base,4 flatfaces, 6 edges and 4 vertices
