Bot, Jordan purchased a piece of fabric that is 18 cm by 18 cm in order to make a tent for her little sister’s dolls. Using the dimensions for the tent shaped as a triangular prism, how much fabric will be left over?

As a Language model AI, I don't have enough information to solve this problem. It is necessary to know the dimensions of the triangular prism formed by the fabric to calculate the surface area and determine how much fabric will be left over.
