Nothing much. A base of a cuboid has 4 sides and there are no triangular faces.
4 faces. The number of faces on a pyramid is one more than the number of sides of the base. A triangle has 3 sides, therefore a triangular pyramid has 3 +1 = 4 faces.
pyramid
A square pyramid has a base with 4 equal sides and triangular faces.
6 vertices, 2 triangular faces, 3 rectangular sides, 9 edges
If you mean a triangular pyramid then it has four faces, one base and three sides.
Faces = sides = 5. Edges = 8

A triangular prism, a triangle base and three triangular faces (a tetrahedron)The figures below do not strictly have a "base" but they are composed entirely of trianglesAn octohedron (eight sides)An isocahedron (20 identical equilateral triangular faces, 30 edges and 12 vertices)Any of a number of deformations of the above
In a triangular based pyramid, the three faces that form the base are perpendicular to the apex of the pyramid, which means they have pairs of perpendicular sides. The other three faces, which are triangular, do not have pairs of perpendicular sides.
5 faces (sides) 9 edges 6 vertices
It has four faces. One on bottome and three sides.
It has 5 SIDES
