This is really very easy. All you have to do is insert the measurements into the equation and do the math. Here is an example:

Here is some new data:
WIDTH = 34 cm
DEPTH = 4 cm
SPEED= 5 cm/sec

Here is what the equation should look like:
EQUATION: ((34 + (34 x .7)) x 4 / 2) x (5 x .7)= 404.6

The answer is 404.6 cc/second.

Don't forget to label your answer with a unit of measurement. In this case, it is cc/second.
