    How many different runs possible

    Hello, got a bit confused on how to solve this problem, so thought I would ask:
    A chemical engineer is designing an experiment to determine the effects of temperature, stirring rate, and type of catalyst on the yield of a certain reaction. She wants to study five different reaction temperatures, two different stirring rates, and four different catalysts. If each run of the experiment involves a choice of one temperature, one stirring rate, and one catalyst, how many different runs are possible?
