Answer the following questions to determine why Euler’s

Question

formula continues to hold for the polyhedron formed by
cutting corners off of an octahedron, as in Figure 11.35(b):
a. For an octahedron V = , ____,F = ____, and E =
_____.
b. When you slice off one corner of the octahedron,
you (gain or lose) ____ vertices, (gain or lose) ____
faces, and (gain or lose) ____ edges.
c. Therefore, the total change in V is ____; the total
change in F is ____; and the total change in V + F is
____.
d. The total change in E is ____.
e. What does the comparison of the total change in V + F
to the total change in E tell you?
