Like all prisms you find the area of one of the triangular faces and then multiply by the height.

Prisms come in many shapes and sizes but all prisms must have flat sides - no curved sides so a Pyramid having flat sides and no curves is a prism. * * * * * That is utter rubbish. Both pyramids and prisms are polyhedra. That means they are solid shapes bounded by plane faces. Neither of them can have curved faces. A pyramid has one polygonal base and triangular faces that rise from the base and meet at an apex. A prism has two congruent parallel bases that are linked together by rectangular faces. Both terms are generic: they do not specify the polygonal bases.
No, not all prisms are cylinders. A prism is defined as a polyhedron with two parallel, congruent bases connected by rectangular faces, while a cylinder is a specific type of prism with circular bases. Therefore, while all cylinders can be classified as prisms, not all prisms fit the cylindrical shape.
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.
In a tetrahedron all the triangles have to be congruent. In a Triangular Pyramid, the lateral faces are all congruent to each other, but not always with the base triangle. Not necessarily. The lateral faces need to be congruent if it is a right pyramid, not otherwise. The apex of the pyramid need not be directly above the centre (however defined) of the base. Think of a triangular pyramid doing an impersonation of the Leaning Tower of Pisa!
The 3D shapes that have all their faces equal to their base are known as regular polyhedra. Specifically, these include the tetrahedron (4 triangular faces), cube (6 square faces), octahedron (8 triangular faces), dodecahedron (12 pentagonal faces), and icosahedron (20 triangular faces). Each of these shapes features congruent faces that exhibit symmetry.
