Refraction problem 23

The container has the shape of a cube with an edge of a length of . A laser beam is directed from the upper left edge of the container so that it hits the lower right edge of the container. A small metal object is placed to the left of the lower right edge. To what height do we have to pour water into the container so that the beam hits the metal object? The refractive index of water is 1.33.
