<PRE><B>Question 1182459</B>
&lt;br&gt;
Draw a picture, at least in your mind....&lt;br&gt;
Vertices: n sides on the base, so there are n vertices on the base; then just one more -- the peak of the pyramid.
ANSWER: (n+1) vertices&lt;br&gt;
Edges: n sides of the base, each of which is an edge of the pyramid; then one edge from each of the n base vertices to the peak.
ANSWER: n+n=2n edges&lt;br&gt;
Faces: the base, plus n triangular faces.
ANSWER: (n+1) faces.&lt;br&gt;
Note those numbers satisfy the Euler formula:&lt;br&gt;
edges = faces plus vertices minus 2&lt;br&gt;
2n = (n+1)+(n+1)-2&lt;br&gt;
