1.A furniture store sells couches that are available in 3 different styles, 7 different colors, and 2 different sizes. How many different couches are available?
- If I multiply all of these, would that give me the answer? If so, the answer would be 42.

2.In how many different ways can 6 students stand in a row of 6?

Thanks
