A wooden ramp would likely be more efficient for pushing a box up, compared to a gravel ramp. This is because a wooden surface tends to provide more stability and traction for the box as it is being pushed up the ramp. Gravel, on the other hand, can be loose and uneven, making it more difficult to push the box up without slipping or losing control. Additionally, wooden ramps are typically smoother and have a more consistent incline which can make it easier to push the box up without as much effort.
