There is a wooden cube with faces painted in green. Its edge is \(3\,\mathrm{cm}\) long. Imagine we cut the cube into small unit cubes with the edge length of \(1\,\mathrm{cm}\) and we select one of the unit cubes at random (see the picture). What is the probability of selecting an unpainted cube?
\( \frac{1}{27}\)
\( \frac{3}{27} = \frac{1}{9}\)
\( 0\)
\( \frac{1}{6}\)
