How much work must be done in producing a conical heap of sand of base radius 1.2 meters and height 1 meter? The specific weight of sand is 2 grams per cubic centimeter. You may assume that all the sand is taken from the surface of the earth (that is, from height 0 meters). I have no idea how to set up the problem...once it's set up i'll be able to do the math, but i'm just stuck right now. Any suggeestions/help is greatly appreciated. Thanks.
