An open box is to be made by cutting away identical squares from each corner of a 4m by 4m piece of metal and then folding up the resulting sides. What size square should be cut from each corner to produce a box of maximum volume? What would be the maximum volume? ​

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
