Surface area   = base area   + area of 4 congruent triangles forming the sides

 

Base area  =  area of a square =  (10 * 10 )  = 100 in^2

 

Area of each triangle  = (1/2) (base) (height) =  (1/2) (10) (9)

So...total area of sides =  4 (1/2) (10) (9)  = 2 * 10 * 9  = 180  in^2

 

So.....what's the answer, Nick ???
