An 18 in. by 16 in. rectangular piece of cardboard is used to make an open-top box with a volume of 336 in. by cutting identical squares, of side length x inches, from each corner. A diagram is shown below. 3 ? 18 in. 12. A polynomial equation that can be used to determine the dimensions of the box is A. x(18– 2x)(16 – 2x) + 336 = 0 B. x(18– 2x)(16 – 2x) – 336 = 0 C. 2r(18–x)(16 – x) +336 = 0 D. 2r(18–x)(16 – x) – 336 = 0 16 in.
