    accurate results I managed to go to fifth decimal place where the value for c was, yet even this is not totally accurate as there will be a much larger number of decimals in the c column to get the maximum number for V.

  2. Open Box Problem.

    I am going to start off by looking at whole numbers. Using the formula: Volume = X(L-2X)^2 ^ I used these formulae to construct a spreadsheet, which would allow me to quickly and accurately calculate the volume of the box for cut-off size 1cm^2 to 19cm^2.

  1. Open box Problem.

    Then we get the following results: X(cm) X(12cm-2X)(cm) 1 100 2 128 3 108 4 64 5 20 We found that 2 is the biggest value whereas we can get the biggest volume in integer. To get a more accurate result, we have to try 1 decimal place.

  2. Open Box Problem

    1. The size of the cut-off is the same size as the height of the box 2. The initial sizes of the length and width have decreased by 2 times the size of the cut-off So, when the initial piece of card is square, the formula for the volume can be written: Volume = (Length-2*Cut-off)
