Question

Erin the ant starts at a given corner of a cube and crawls along exactly 7 edges in such a way that she visits every corner exactly once and then finds that she is unable to return along an edge to her starting point. How many paths are there meeting these conditions? A. 6B. 9C. 12D. 18E. 24

Answer 1

Answer:

A. 6

Step-by-step explanation:

Taking into account that the starting point (given corner) is the first edge and between each edge the ant walked is 1 path, we subtract of the total number of edges the one, because between each corner or edge there is one path, so the answer is seven minus one equal six, 7-1=6
