Let $\"+x+\"$ = the width in inches
\n" ); document.write( " $\"+x+%2B+2+\"$ = the height in inches
\n" ); document.write( " $\"+25+\"$ inches = the length
\n" ); document.write( "----------------------------------------
\n" ); document.write( " $\"+x%2A%28+x+%2B+2+%29%2A25+=+9000+\"$ in3
\n" ); document.write( " $\"+%28+x%5E2+%2B+2x+%29%2A25+=+9000+\"$
\n" ); document.write( " $\"+25x%5E2+%2B+50x+-+9000+=+0+\"$
\n" ); document.write( " $\"+x%5E2+%2B+2x+-+360+=+0+\"$
\n" ); document.write( " $\"+%28+x+%2B+20+%29%2A%28+x+-+18+%29+=+0+\"$
\n" ); document.write( " $\"+x+=+-20+\"$
\n" ); document.write( " $\"+x+=+18+\"$ ( can't use the negative result )
\n" ); document.write( "------------------
\n" ); document.write( "Width = 18 in
\n" ); document.write( "Height = 20 in
\n" ); document.write( "-------------------
