Solve the problem. A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 13 inches by 26 inches by cutting out equal squares of side x at each corner and then folding up the sides as in the figure. Express the volume V of the box as a function of x. A) V(x) - (13 - 2x)(26 - 2x) B) V(x) - x(13 - 2x)(26 - 2x) O V(x) = (13 - x)(26 - x) D) V(x) = x(13 - x)(26 - x)
