By cutting away an x-by-x square from each corner of a rectangular piece of cardboard and folding up the resulting flaps, a box with no top can be constructed. If the piece of cardboard is 54 inches long by 30 inches wide, find a function in the variable x giving the volume of the resulting box. Volume, as a function of x = X Determine the domain of the function for volume. Enter your answer using interval notation. Domain of the function for volume = X
