F$-10$ A highway grade intersection will require $1200000m^3$ of compacted fill to be compacted to a porosity of $42\%.$ Two sources of borrow material are available. The void ratio of the soils at both available sites are given below, along with the cost of excavating, hauling, and compacting at the project site.

From which site can the project fill be obtained the cheapest?
