merlin--You probably know that you can find almost anything on

www.google.com . For example

http://microgeometry.netfirms.com/co...html#frustcone (look under frustrum cone)

which I got from one of the hits at

http://www.google.com/search?hl=en&i...=Google+Search
Then she will also need to convert the volume to liters.

But doesn't she have a geometry book?

P.S. As you can see, integrals are not involved. This problem is solved with a simple equation from geometry, not calculus. But maybe there are other problems outside geometry?? Again, a book would help (or google). To automate, try a scientific calculator.
