document.write( "Question 1199113: The following problem is often used in textbooks using different measures. \r
\n" ); document.write( "\n" ); document.write( "An open box is to be constructed from a square piece of sheet metal by removing a square of side 1 foot from each corner and turning up the edges. If the box is to hold 4 cubic feet, what should be the dimensions of the shert metal?\r
\n" ); document.write( "\n" ); document.write( "Let me see.\r
\n" ); document.write( "\n" ); document.write( "I can label the length of a side of the square piece of metal as x.
\n" ); document.write( "The box will be of height 1 foot, and it's square base will measure (x - 2) on each side. The volume V of the box is V = (x - 2)(x - 2) • 1 or (x - 2)^2.\r

\n" ); document.write( "yes, that is right so far\r
\n" ); document.write( "\n" ); document.write( "plug in given The volume \"V\"\r
\n" ); document.write( "\n" ); document.write( "\"V=%28x-2%29%5E2+\"\r
\n" ); document.write( "\n" ); document.write( "\"4=%28x-2%29%5E2+\"\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2+-+4x+%2B+4+=+4\"\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2+-+4x+%2B+4+-+4+=+0\"\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2+-+4x+=+0\"\r
\n" ); document.write( "\n" ); document.write( "\"x%28x+-+4%29+=+0\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two solutions\r
\n" ); document.write( "\n" ); document.write( "\"x+=+0\"->disregard\r
\n" ); document.write( "\n" ); document.write( "and\r
\n" ); document.write( "\n" ); document.write( "\"x+=+4\"\r
\n" ); document.write( "\n" ); document.write( "so, the dimensions of the sheet metal are \"4ft\" by \"4ft\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
