Cost of construction of triangular prism.

A hollow equilateral triangular prism has a fixed volume of 1.8 cubic metres. The sides of the triangle have the length P. To build the prism, one of the triangular faces costs 1.2 times what the remainder of the prism (excluding the base) costs, and the base costs 1.5 times what the remainder of the prism (excluding the previously mentioned triangular face) costs. QUESTION: How can the cost (C) of the entire prism be expressed in terms of P (the side length of the triangle)? Thank you.
