Answer:
C
Step-by-step explanation:
A rational number can be made into a fraction
0.21 = 21/100....so it is rational
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 is8 faces
