Answer:
48
Step-by-step explanation:
When there are several things to combine, and each one can be done in a number of ways, the total number of combinations is the product of all the ways of each item.
There are 4 colored sheets.
There are 6 shapes of eyes.
For each color of sheets, he can cut the eyes in 6 ways, so just taking into account the sheets and the eyes, there are
4 * 6 = 24 different combinations of sheets and eyes
Now for each of the 24 different combinations of sheets and eyes, he can choose from 2 different shoes.
4 * 6 * 2 = 48
The number of different ways is 48.
