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