Answer: 3.92 N.

Explanation:

Your box weighs 400g, or 0.4kg. In order to lift it, you need to overcome the force of gravity. F = ma, and acceleration due to gravity is - 9.8 m/s^2. So gravity acts on the box with a force of 0.4 kg * - 9.8 m/s^2 = - 3.92 N. A force of + 3.92 N is required to overcome this.
