I am stuck on finding a formula to solve the number of grains.  I have an idea, but if you can just give me the steps to solve the equation without giving the answer.   The question is The Sahara Desert covers about 8.3x10^13 squart feet.  the average depth of the sand in the Sahara Desert is 200 ft. A grain of sand has a volume of approximately 1.3 X 10^-9.  What would be the best estimate of grains in the sarah desert.  I understand that the volume of a cube is given which is approx 1.3 X10^-9.  Would I use the formula for the density?<BR>\n" );
