What is the total area of one face of the pyramid? what is the total surface area of the faces of the pyramid, not counting the bottom? (Hint: the bottom of the pyramid is a square.)

Pyramid=4 triangles and 1 square base

area of triangle = (1/2) bh

4 triangles

therefor

area of 4 triangles=4 (1/2) bh=

area of 4 triangles=area of faces of pyramid

area of faces of pyramid=4/2bh

area of faces of pyramid=2bh

h=slant height

2bh is answer where h=slant height and b=base legnth
