wood
Gopher wood. After God gave Noah the directive to build the Ark. Noah went to his sons (Shem, Ham and Japheth) and said "GO FOR WOOD" and they did.
It's a fictional story. Therefore I'm sure we have no clue.
We know the dimensions of Noah's ark, but there is no way of knowing the number of trees since we are not able to identify the type of wood used, nor the size of each tree. It would have been in the hundreds at least, possibly thousands, which is why it took so long to build.
The ark of the Book of Genesis in the Holy Bible was constructed of Gopher wood.
Noah made the ark of cypres wood.
Wood.
Noah is never instructed to build an ark in the Yahwist account.

I think God told Noah to build the ark. Haven't you ever heard of Noah's Ark? It's a Bible story I think.
