As long as only gravity is acting on the cube, it should follow the general rules of [Projectile $$anonymous$$otion][1]. If you know the cube's initial speed and firing angle, you can calculate the distance it will travel using the projectile motion equations. Then, as long as you know the direction the cannon is facing, as say an angle from the positive x-axis, you can convert that to x-y coordinates, which will be the landing position.
