"How long does it take?" is the correct sentence. "How long did it?" is incorrect.
"How long does it take?" is a question that asks for the amount of time required to complete an action or process. The subject of the sentence is "it," which refers to the action or process being questioned. The verb "take" is in the present tense, indicating that the question is about the current or general amount of time required.
"How long did it?" is an incomplete sentence that does not make sense. The verb "did" is in the past tense, which would be used to ask about the amount of time required in the past. However, the subject of the sentence is missing, and the sentence is not grammatically correct.
Therefore, the correct sentence is "How long does it take?"
