1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals

(units)
Area of 1 lateral side of pyramid ABCDE is

so the total lateral area is

(units squared)
and the total surface area is

(units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is

so the total area of the second pyramid is

So 2 things can be said about the areas:
