Easiest way to get the surface area of the lateral square pyramid is by using the formula:
\(A_{L} = a \sqrt{ a^{2}+4 h^{2} }\)
a = Base edge = 646 ft
h = Height = 350 ft
Using the formula:
\(A_{L} = 646 \sqrt{ 646^{2}+4 350^{2} }\)
[tex]A_{L} = 6.15335×10^{5} square feet
[tex]A_{L} = 615335 square feet
