2 shapes, a triangle, and a rectangle.since it is a prism, it is like a pyramid, 4 of the faces are triangles,but the base is a rectangle, hence the name rectangularprismtherefore, 2 shapes

Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
Prefices are used to indicate the number of sides, angles, faces or solid angles (in 3d objects).
It is important to learn and remember the name of 3D shapes. A 19 faced 3d shape is called a nonadecahedron.
All except the base are always triangles; the shape of the base gives the name to the pyramid; eg a pentagonal pyramid has a pentagon as the base and five triangular faces; a triangular pyramid has three triangular faces and also has a triangle for the base.
There are many possible shapes. The most general, which has a specific name is a parallelopiped. A cube is a special case of a parallelopiped.
In geometry, a deltahedron (plural deltahedra) is a polyhedron whose faces are all equilateral triangles. The name is taken from the Greek upper case delta (Δ), which has the shape of an equilateral triangle.
There is no standard formula since a polyhedron can have a number of different shapes. A hexahendron, for example, can be a cuboid (6 rectangular faces) or a triangular dipyramid (6 triangular faces) or others. The number of different shapes increases rapidly as the number of sides (which determines the name) increases. The only solution is to calculate the area of each face and add them together.
Triangular based pyramid. If you're referring to a tetrahedron, then for polyhedrons (3 dimensional shapes), they are actually called faces, rather than sides.
The name of the shapes formed are triangles.
