This problem can't be solved, because it is an invalid problem. For the following reasons:
>The portals always need to be stationary in relation to each other.
>You cannot freely switch between frames of reference, since the cube's and portals' frames of reference aren't inertial in relation to each other. This means that either the cube moves and the portals are stationary, or the portals move(with the same velocity, always in the same direction) and the cube is stationary.

Only idiots try to do solve invalid problems
