To add to Andrea's answer, the following usage in the passive can occasionally be found, although it might be frowned upon by traditionalists. The United States is comprised of fifty states. (The fifty states make up the US) In this sense, it's used with the preposition "of".

Привет! Слова "включать" и "состоять" взаимозаменяемы? (Разница лишь в "из") Соединённые Штаты включают пятьдесят штатов Соединенные Штаты состоят из пятидесяти штатов

Hi Nazar, yes they quite are with comprise being more formal but both the examples you wrote are correct.
