As you cut those 2 inch by 2 inch squares from the corners, you are left with a center square surrounded by rectangular flaps 2 inches wide, that will fold up to make the sides of the box.
The middle part that will be the bottom of the box is a square with sides measuring (x-4) inches.
The volume of the box is the surface area of the green base times the height ,
