Final answer:
The force required to push a box up a ramp is determined by the weight of the box, not the dimensions of the ramp.
Step-by-step explanation:
The statement is False.
The force required to push a box up a ramp is determined by the weight of the box, not the dimensions of the ramp. In this case, the weight of the box is 300 N, so the force required to push it up the ramp would also be 300 N. The length and height of the ramp do not affect the force required.
