It helps to draw this
\n" ); document.write( "The diagonal of the floor of the box is the sqrt (5^2+14^2)=sqrt (221)
\n" ); document.write( "That hypotenuse becomes the leg of a triangle whose other leg is the unknown height and the diagonal is the pen itself.
\n" ); document.write( "so sqrt(221)^2+h^2=15^2
\n" ); document.write( "221+h^2=225
\n" ); document.write( "h=2 cm.
\n" ); document.write( "
