I don't actually know what an inclined plane is. But I know what a truck is.
An inclined plane is a surface that is not horizontal (level), with one end higher than the other. Pushing a broken down car is much easier and takes less effort downhill, than to push the same car uphill.
To calculate the force needed to push the box up the inclined plane, you need to consider both the weight of the box acting downwards and the component of the weight parallel to the incline. You would use the formula: Force = Weight * sin(angle), where the weight of the box is 250 N and the angle of the incline can be calculated using trigonometry (angle = arctan(height/length)).
It usually form an angle of 90 on resting on any vertical surface
Not enough information. That would depend on the angle of inclination, the coefficient of friction, and whether you are pushing it up or down the plane. Also on gravity, but that can be assumed to be more or less constant, at about 9.8 N/kg.
Reducing the length of the inclined plane would require less effort to move an object up it. This is because a shorter inclined plane means a shorter distance over which the object needs to be lifted, reducing the work required to overcome gravity.
Using mechanical advantage to offer a large lifting force from a much smaller input force, essentially an inclined plane or wedge.

The function of an inclined plane is actually quite simple. This inclined plan is often used to transport items up or down much like a ramp.

It is a simple machine which can be used to apply a relatively weaker force over a longer distance instead of a much greater force over a short, direct distance.
As an inclined plane gets shorter, the angle gets steeper and the effort becomes greater.
Like any simple machine, it spreads the work over a greater distance. For example, if you want to raise a load five feet, by using a 30° inclined plane, you spread the same work over ten feet, so only half as much force is needed.
