Congruent squares of length x are cut from the corners of a 10-inch by 15-inch piece of cardboard to create a box without a lid. Write an expression in terms of x for the length, the width, and the height of the box. Write a function, V(x), in terms of x for the volume of the box. Leave your answer in factored form. Express the reasonable domain of V(x) as an inequality and in interval notation.
