Remember that the volume of a rectangular prism (a box) is given by:
\n" ); document.write( "\"V+=+L%2AW%2Ah\"
\n" ); document.write( "In this case, you have:
\n" ); document.write( "L = x inches.
\n" ); document.write( "W = 2x inches.
\n" ); document.write( "h = (3x-5) inches.So the volume of the box in your problem can be expressed by the function:
\n" ); document.write( "\"V%28x%29+=+x%282x%29%283x-5%29\" or
\n" ); document.write( "\"V%28x%29+=+6x%5E3-10x%5E2\" so...
\n" ); document.write( "\"V%283%29+=+6%283%29%5E3-10%283%29%5E2\"
\n" ); document.write( "\"V%283%29+=+6%2827%29-10%289%29\"
\n" ); document.write( "\"V%283%29+=+162-90\"
\n" ); document.write( "\"V%283%29+=+72\"cubic inches.
\n" ); document.write( "
\n" );
