pyramids

=
 *​ The base is a polygon (a straight-sided shape ) =====

the area of a pyrimd is- lenth*with
because the pyrimid sits on a sqaure and we all know that a sqaures area is l*w so for that is how you get the area of a pyrimid

To find the total surface area of a pyramid, use this equation: To find the volume of a Pyramid, substitute into this equation: V=1/3Bh B=base area h=height of pyramid Surface Area = B + 1/2 *P * s B = base area P = perimeter of the base s = slant height
