Question

what is the formula for surface area of pyramid?

Answer 1

Total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base.

The general formula for the lateral surface area of a regular pyramid is L.S.A.=12plL.S.A.=12plwhere pp represents the perimeter of the base and ll the slant height.

Answer 2

A pyramid is a polyhedron madeup of a polygnal base and an apex. A lateral face is a triangle formed by the base edge and apex of each lateral face. It has a polygonal basic and is a conic solid. There are $n+1$ vertices, $n+1$ faces, and $2n$ edges in a pyramid with an $n$ sides base.

The formula of surface area of a pyramid is:

Surface area of pyramid $=\frac{1}{2}$ perimeter of the base × slant height + base

where

$P$ Perimeter of the base.

$L$ Slant height

$B$ Area of Base
