It does not take it 500n to lift it straight up to 3m... It takes 1500 Joules to lift it to an altitude of 3m... ( 2:35 )

@googagaz Hey, thanks for checking out my video. The question I think you were referring to asked how much force was necessary to move the box up the incline with the mechanical advantage. I showed the force necessary to lift it straight up for comparison. You are correct about the PE, but that wasn't what the question was asking.
