Algebra.Com's Answer #59694 by Mona27(45)![]() ![]() ![]() You can put this solution on YOUR website! If you can imagine the cardboard 6 feet by 8 feet, and you're cutting squares of side x from each corner. \n" ); document.write( "The length of the box would be 8-2x, and the width would be 6-2x, and the height is x. \n" ); document.write( "So the volume is \n" ); document.write( "The relevant range of values of x are from 0 to 3, since you can't have the cut-out squares having a larger side than half the width of the original rectangular cardboard.. \n" ); document.write( "The graph looks like this: \n" ); document.write( " \n" ); document.write( "And the value of x which will give the maximum volume is approximately 1.13 \n" ); document.write( " |
