Answer
A big rock will require more force because the force required to push an object depends mainly on its mass (weight) and the friction between the object and the ground.
As a rock is made of solid minerals, so it is much heavier and denser than a carton (which is mostly hollow or filled with light material). Since, the rock has more weight, the frictional force between the rock and the ground is also greater. Hence, it needs a larger push to move compared to the carton.
