Question 1071143
The surface area of a square pyramid is divided into 2 major sections:

The area of the base and the area of the area of the 4 faces.

The area of the base is the area of a square with side length 8, or {{{8*8 = 64}}}
The area of one face is the area of a triangle with base 8 and height 14, or {{{(8*14)/2}}} or 56.
The area, then, of 4 faces is {{{56*4 = 224}}}

So, the total area is {{{64 + 224 = 288}}}
