Algebra.Com's Answer #744017 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! the volume is x (the height or depth)(12-2x)(8-2x) \n" ); document.write( "that is 4x^3*40x^2+96x \n" ); document.write( "and that equals 36 \n" ); document.write( "x=0.46 in and x=3 in \n" ); document.write( "Lengths can be 6 inches (12-2(3)) and 11.08, with width 3 in \n" ); document.write( "corresponding widths would be 2 and 7.08, with width 0.46 in\r \n" ); document.write( "\n" ); document.write( " |
