The mass of a person together with the box will be equal to:
70 + 20 = 90 kg.
According to Newton’s third law, the force with which a person presses on the Earth will be equal to the force
its severity, which, in turn, is determined by the formula:
F = m * g, where m is body mass, g is gravitational acceleration.
F = 90 * 10 = 900 N.
