Summary: The theory of \(p\)-adic fractal strings and their complex dimensions was developed by the first two authors [J. Fixed Point Theory Appl. 3, No. 1, 181–190 (2008; Zbl 1234.28011); \(p\)-Adic Numbers Ultrametric Anal. Appl. 1, No. 2, 167–180 (2009; Zbl 1187.28014); Contemp. Math. 551, 163–206 (2011; Zbl 1276.37053)], particularly in the self-similar case, in parallel with its archimedean (or real) counterpart developed by the first and third author in [Fractal geometry and number theory. Complex dimensions of fractal strings and zeros of zeta functions. Boston, MA: Birkhäuser (2000; Zbl 0981.28005); Fractal geometry, complex dimensions and zeta functions. Geometry and spectra of fractal strings. New York, NY: Springer (2006; Zbl 1119.28005)]]. Using the fractal tube formula obtained by the authors for \(p\)-adic fractal strings in [“Minkowski dimension and explicit tube formulas for \(p\)-adic fractal strings, preprint, (2012)], we present here an exact volume formula for the tubular neighborhood of a \(p\)-adic self-similar fractal string \(\mathcal L_p\), expressed in terms of the underlying complex dimensions. The periodic structure of the complex dimensions allows one to obtain a very concrete form for the resulting fractal tube formula. Moreover, we derive and use a truncated version of this fractal tube formula in order to show that \(\mathcal L_p\) is not Minkowski measurable and obtain an explicit expression for its average Minkowski content. The general theory is illustrated by two simple examples, the 3-adic Cantor string and the 2-adic Fibonacci strings, which are nonarchimedean analogs (introduced in [Zbl 1234.28011; Zbl 1187.28014]) of the real Cantor and Fibonacci strings studied in [Zbl 0981.28005].For the entire collection see [Zbl 1276.00022].
