I need to vary the surface area by choosing different size beaker.
I will put liquid in there so it would have to be volume??cm^3?

But the question is how can I calculate the surface area of the beaker ???
The key thing here is the container...

Examples:
27cm^3???
250 ml beaker???
Small test tube??

I know that my explanation may not be clear but... I hope you understand this....

It isn't and I don't.
The surface area of liquid in a beaker would be done this way.
Measure the diameter of the beaker. Then pi*r^2 = area. Yes, you can vary the surface area by changing the size of the beaker. That will work for any cylindrical container. It would be different for a rectangular or square container. This may not help; if not, try explaining again. Perhaps I just thought I didn't understand. :-)
