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.

The Dewey Decimal Classification System is a method used
to calssify books in the library. It was named after Melvil Dewey who developed
it in 1876. The system uses numbers to organize the subjects of each nonfiction
books and are divided into 10 main subject groups called categories. Each category
is presented by a figure starting from 000 to 999. Each number presents a
special topic. Books with the same number are placed in alphabetical order by
the last name of the author. The first digit of a three digit number signifies
the main class. Suppose you have 500, the 5 in signifies natural sciences and
mathematics. The second digit signifies the division and the last digit signifies
the sections.
