What does pyramid mean In maths?

In mathematics, a pyramid is a three-dimensional geometric shape that has a polygonal base and triangular faces that converge to a single point called the apex. The number of triangular faces corresponds to the number of sides of the base. Common types of pyramids include square pyramids and triangular pyramids, which are named based on their base shapes. Pyramids are characterized by their volume and surface area formulas, which depend on the base area and height.
