as illustrated and explained here:
http://math.about.com/od/formulas/ss/surfaceareavol_5.htm
the area is just the square area of the base plus the areas of the four triangles forming the sides. And, as we all know, the area of a triangle is 1/2 base * height (the slant height of the pyramid). So,
A = b^2 + 2bs = 15.2^2 + 2(15.2)(15.2) = ?
what is the surface area of a square pyramid if the slant height is 15.2 m and the base is 15.2 m?
please explain it to me. this is not homework, it is a practice question and I do not understand how to solve it. Someone PLEASE help!
