What is a rectangular pyramid?

A rectangular pyramid is a polyhedron with a rectangular base and four triangular faces that meet at a point called the apex. It has eight edges and five vertices. The height of a rectangular pyramid is the perpendicular distance between the base and the apex. The volume of a rectangular pyramid can be calculated using the formula V = (1/3) * base area * height. The surface area of a rectangular pyramid is the sum of the areas of the base and the four triangular faces. Rectangular pyramids are commonly used in architecture and geometry.
