u got them wrong
I apologize for the incorrect response.
In this scenario, if the box is stationary and the forces are balanced, the box must exert an equal and opposite force to counteract the upward forces of the ropes. Therefore, the box exerts 10 N of force upward. Thank you for bringing this to my attention.
