Hi,

Surface Area: Add the area of the base to the sum of the areas of all of the triangular faces.
h = 14ft
Area[Base] = 36ft^2
Area[Triangular face]= (1/2)(6ft)(s) where s is slant height = sqrt%2814%5E2+%2B+3%5E2%29+=+sqrt%28205%29
S%5BArea%5D+=+36f%5E2+%2B+4%283sqrt%28205%29%29ft%5E2+=+36ft%5E2+%2B+12sqrt%28205%29ft%5E2
