The surface area of the box of cereal displayed below is 2x^2+48x+88.what is the value of x if the box of cereal has an area of 192in^2?

Step-by-step explanation:

Surface area is given by 2x²+48x+88

We need to find x when surface area is 192.

                          A = 2x²+48x+88

                         2x²+48x+88 = 192

                         2x²+48x- 104 = 0

                         x²+ 24x - 52 = 0

                        ( x - 2 ) ( x + 26 ) = 0

                       x = 2   or  x  = -26 not possible

Value of x is 2
