Sand falls from a conveyer belt at a rate of 15m^3/min. How fast is the height changing when the pile is 2m high?

This is a related rates problem using cones. I am in Calculus.

There's not enough information.  In order to solve this you need to know something about the shape of the cone, such as the ratio between the height and the diameter or radius of the base.
