document.write( "Question 921759: I need help with finding the dimensions of a box with a volume of 720 cubic inches. I drew a rectangular box and labeled the sides with the info I got. The width is 3x its height and its length is 11 inches more than its height .i took 3 and multiplied it by 4 and took 4 and 4 added together and got 8. That is all I have done. \n" ); document.write( "

Language skills are important:
\n" ); document.write( "The width is 3x three times its height, and its length is 11 inches more than its height.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Length = h+11
\n" ); document.write( "Width = 3h
\n" ); document.write( "Height = h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Volume of the box given as 720 cubic inches.
\n" ); document.write( "L*W*H=VOLUME\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight_green%28%28h%2B11%29%283h%29h=720%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3h%5E2%28h%2B11%29-720=0\"
\n" ); document.write( "\"3h%5E3%2B33h%5E2-720=0\"
\n" ); document.write( "\"h%5E3-11h%5E2-240=0\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You could use Rational Roots theorem and synthetic division...
\n" ); document.write( "but a quick check in google search engine's graphing capability shows \"h=12.5\"
\n" ); document.write( "
\n" );
