the weight is proportional to the volume of the model\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the volume is proportional to the cube of the length\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the weight is proportional to the cube of the length __ 12 feet is 144 inches\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let x=weight __ 2/8^3=x/(144)^3 __ 2(18)^3=x
\n" ); document.write( "
\n" );
