## Abstract The cube polynomial __c__(__G__,__x__) of a graph __G__ is defined as $\sum\nolimits\_{i \ge 0} {\alpha \_i ( G)x^i }$, where α~i~(__G__) denotes the number of induced __i__‐cubes of __G__, in particular, α~0~(__G__) = |__V__(__G__)| and α~1~(__G__) = |__E__(__G__)|. Let __G__ be a medi
