is a polyhedron with a polygonal base and triangular
faces equal to the number of sides in the base. All the triangular faces meet at a single point called the apex
The faces of the pyramid connect the bases with the apex. If the pyramid is oblique leaning to one side or the base is irregular, there is no straightforward way to find the surface area. Each triangular face will be a different shape and size, so you would have to find the area of each using whatever measurements you are given.Types of Pyramids
There are many types of Pyramids, and they are named after the shape of their base. Surface Area
of a Pyramid is the sum of the area of the polygonal base
and the area of the triangular faces.
a - apothem length of the pyramid.
b - base length of the pyramid.
