We present an extension of the classical isomorphic classification of the Banach spaces C([0,α]) of all real continuous functions defined on the nondenumerable intervals of ordinals [0,α]. As an application, we establish the isomorphic classification of the Banach spaces $C(2^{𝔪} × [0,α])$ of all real continuous functions defined on the compact spaces $2^{𝔪} × [0,α]$, the topological product of the Cantor cubes $2^{𝔪}$ with 𝔪 smaller than the first sequential cardinal, and intervals of ordinal numbers [0,α]. Consequently, it is relatively consistent with ZFC that this yields a complete isomorphic classification of $C(2^{𝔪} × [0,α])$ spaces.
