The foundation has:
+45%2A25%2A6+ cubic feet of dirt
---------------------------
One cubic yd = +3%2A3%2A3+=+9+ cubic ft
5 cubic yds = +5%2A9+=+45+ cubic ft
-----------------------------------
The cost to remove the dirt is:
+%28+%28+45%2A25%2A6+%29+%2F+45+%29%2A15+
+%28+45%2A25%2A6+%29+%2F+3+
+45%2A25%2A2+=+45%2A50+
+45%2A50+=+45%2A%28100%2F2%29+
+4500%2F2+=+2250+
$2,250
