Question

it is easier to push a lighter box then a heavy box on same floor

Answer 1

due to its mass that is easier to push lighter box then a heavy box on same floor

Answer 2

We know that F=ma. Here, acceleration is constant i.e. 9.8 m/s^2, which is acceleration due to gravity, but mass varies. So, in the case of heavy box, We need a greater force to push it but not for the lighter box. Thus, it is easier to push a lighter box than a heavy one on the same floor.
