I usually ask people to imagine they are putting a rope tight around the earth, following the equator (idealized sphere). Then they add 1 meter to the rope (it is now longer by a meter) and spread it around the earth uniformly (it hovers above the earth, everywhere at the same distance from the earth) Estimate that hovering distance. Try yourself to estimate it, then make the calculation.
