The word [totally] means [completely] sometimes, in Chinese, says [完全地]or[绝对地].Meaning absolutely for sure. For example, [totally it was a good day] can be translated as[绝对是很好的一天]. The word you said [一共] is [total], not [totally].

Nope, totally does not mean 一共 here. Totally it was a good day = 这是极好的一天。
