At a local toy store, you can build your own stuffed teddy bear. You can choose from 5 colors of bears, 3 different sizes and 12 different t-shirts for the bear to wear. How many different types of bears can you make?

The number of different types of bears that can be made using the given is calculated through the fundamental principles of counting.

n = (number of colors) (number of sizes) (number of t-shirts)

Substituting the known values,

n = (5) (3) (12) = 180

Therefore, there are 180 different types of bears that can be made.
