The surface area of the base is the surface are of a square with a side length of 4 units.
That area is 16 square units:
%284unit%29%284unit%29=16unit%5E2 .
The sides of the pyramid are four triangles with a base length of 4 units, and a height of 8 units.
The surface area of one such triangle (in square units) is
4%2A8%2F2=16
The surface area of all four sides plus the base (in square units) is
4%2A16%2B16=highlight%2880%29
