1. The problem statement, all variables and given/known data a rectangular box with no top is formed by cutting out equal squares from the corners of a square sheet of metal, 10 cm by 10cm, and bending up the 4 sides. What size of square must be removed from each corner to generate a box with a volume of 50cm^3? (Note: there are 2 answers.) 2. Relevant equations Tangent Line Approximation and Newton's Method 3. The attempt at a solution This is a question where I do not know where to start. I know I am supposed to find the height of the box using the volume formula and am given the volume, but I don't know how to calculate the length. To me this seems to be a change in value question, where the volume is changing, but I don't think this is right :tongue:. Could anyone be of assistance here please to get me on the right track for this question? Thanks in advance.
