there are \boxed{} total possible cellphone and case combinations.

Explanation:

Step1: Identify number of phones and cases

There are 3 cell phone versions (6, 7, 8) and 3 cell phone cases (A, B, C).

Step2: Use multiplication principle

The total number of combinations is the product of the number of phone versions and the number of case types. So, we calculate $3\times3$.
