How to explain in simple terms "least action" principle to a person who is not familiar with calculus?

How to explain that the following combination of fundamental constants: c-3/2 G1/2h1/2 = 1.6x10-35 meters has the dimension of length to a person who is not familiar with algebra? (c here is the light speed, h - Plank constant (=hbar), and G - gravitational constant).


How to explain that 10-35meters is about million billions times less than 10-20meters to someone not very familiar with arithmetic?

How to explain that 2x2=4 to a person who does not know arithmetic at all?

Is there a way?
