<p>Hi guys, </p>

<p>I was solving test 6 in blue book and got only this question wrong in the test. I don't understand why I did it wrong though.</p>

<p>Question 17 section 4 test 6 page 717;</p>

<p>17) The three-dimensional figure above has two parallel base and 18 edges. Line segments are to be drawn connecting vertex V with each of the other 11 vertices in the figure. How many of these segments will not lie on an edge of the figure?</p>

<p>Okay my answer is 4,but answer is 8. Here is how I thought about it since the edges where connect to V is two edges,and the vertices are = 6,then 6 - 2 = 4;</p>

<p>two here is the two vertices at the edge of the figure.
Please tell me where did I go wrong here or even if I understood this question correctly.</p>

<p>It’s a 3-d figure – actually a hexagonal prism. They give you a vertex to start with on the upper surface. There are 5 other vertices on the upper surface and 6 vertices on the lower surface. that makes a total of 11 connecting segments that can be drawn. But of those 11, 3 are already edges of the given solid: two are the segments that connect to the two vertices adjacent to the given vertex on the upper surface and one is the segment that heads dierectly down to the lower surface. 11 - 3 = 8 that are not edges of the given solid.</p>

<p>Thanks alot @pckeller can’t believe its a so silly question!:D.</p>
