We know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

V - E + F = 2
clear F
F=2-V+E

in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8

the answer is
8 faces

zubka84 [21]
<u>The possible answers are:
</u>
<u /><u /><u><em /></u>4.21
4.22
4.23
4.24

Explanation:
We want a number between 4 1/5 and 4.25.  We will convert 4 1/5 to a decimal first:

Divide 1 by 5:  1/5 = 0.2.

This makes 4 1/5 = 4 + 1/5 = 4 + 0.2 = 4.2.

We want a number between 4.2, which can be written as 4.20, and 4.25.  Any number between will do, so the possible answers would be 
4.21, 4.22, 4.23, or 4.24.<u />
