So in terms of cubes the prism is 6 cubes high, 3 cubes wide, 2 cubes deep.
\n" ); document.write( "That's a total of \"6%2A3%2A2=36\" cubes.
\n" ); document.write( "The eight corner cubes (C) have three sides painted.
\n" ); document.write( "The twenty edge cubes (E) have two sides painted.
\n" ); document.write( "The eight inner cubes (I) have one side painted.
\n" ); document.write( "\"8%2B20%2B8=36\" so all cubes are accounted.
