Answer:
65
Step-by-step explanation:
Using Euler's Formula, the number of faces is given by: 8.
<h3>What does Euler's Formula states?</h3>
It states that the number of vertices, edges and faces is related by the following equation:
V - E + F = 2.
In this problem, the parameters are given as follows:
E = 15, V = 9.
Hence the number of faces is given by:
V - E + F = 2.
9 - 15 + F = 2
F - 6 = 2
F = 8.
