Abstract We will calculate the weight of lexicographic products of GO-spaces, using this we will see: • the assertion that the weight of the lexicographic product 2 ω 1 is ℵ 1 is equivalent to the Continuum Hypothesis (CH), that is, 2 ℵ 0 = ℵ 1 , • the assertion that the weight of both lexicographic products 2 ω 1 and 2 ω 1 + 1 coincide is equivalent to the assertion 2 ℵ 0 = 2 ℵ 1 , • the assertion that the lexicographic product 2 γ is homeomorphic to the usual Tychonoff product 2 γ is equivalent to γ ≤ ω .
