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.
