Final answer:
The provided reference material does not specify the number of poles used by Gilgamesh to push the boat across the sea. Consult the full text of the Epic of Gilgamesh or academic commentaries for a detailed answer.
Step-by-step explanation:
The question regarding Gilgamesh is a reference to the ancient Mesopotamian text known as the Epic of Gilgamesh, the provided references do not contain specific information about the number of poles Gilgamesh uses to push the boat across the sea. Typically, relevant details regarding specific actions of characters within the text would be found within the epic itself. As the Epic of Gilgamesh is a well-studied text, this information may be available in a full reading of the epic or in academic commentaries on the text.
In this situation, due to the lack of specific details in the provided reference material, I am unable to provide a confident and accurate answer to the question of how many poles Gilgamesh uses to push the boat across the sea. I recommend consulting a complete version of the Epic of Gilgamesh or a scholarly analysis for the precise details sought.
