	Even as a grade school student who literally "didn't know anything
about anything" I did better than that, as did my friends who didn't
know any more.  We usually got two or three inches, and had never heard
of resonance or tuning!!!  Even a simple pencil and paper calculation of
inductance and "guesstimate" of capacitance should get you in the ball
park.
