By cutting out squares of 4cm at each corner
\n" ); document.write( "this reduces the size of the sides by 8cm
\n" ); document.write( "So, dimensions become 12cm by 4cm by 4cm
\n" ); document.write( "Volume = length*width*height
\n" ); document.write( "Volume = 192cm^3
\n" ); document.write( "Hope this helps.
