    Finding two possibilities of depth when volume is given?

    OMG unbelievable. Firstly, I didn't think about setting it equal to 2000 and then moving the 2000 over to make it equal to 0. Secondly, What was also messing me up was that I wasn't sure if looking for roots was the way to solve this, not realizing that was the way to solve it and that I had...

    Finding two possibilities of depth when volume is given?

    The only thing I left out is the beginning format of the V(x) which was: (x)(x+10)(40-(x+x+10)) The x being depth The x + 10 being length The (40 - (x+x+10)) being width(40) minus (depth + length) OK I compact the problem into the below: -2x3+30x2-20x2+300x Now I need a constant to try the...
