| Folded cardboard box math problem...? Hi everyone thanks for taking the time to read my question... Ok so in this problem there is a 10 inch by 20 inch rectangular sheet of cardboard...Six "x-inch" squares are cut out (4 squares in each corner and then two in the middle) in order to turn the flat piece of card board into a folded “pizza-type” box....The question then is what are the dimensions to two decimal places of all possible boxes that will have a volume of 75 cubic inches? Now I ended up trying to solve this by setting up the equation y=x(10-4x)(20-2x) and then graphing this but when I checked my answers I came away totally wrong so if anyone could help me out with the correct way to solve this problem it would be great....thank so much for your time and even if you can't help thanks for reading this far...      |
