Note an octahedron has 8 (oct) sides.
Faces refers to sides = 8
edges are where faces meet = 12
vertices are where edges meet = 6
to count them yourself
picture 2 pyramides with square bases of the same size put together base to base
the square based pyramid (imaging the Great Pyramid of Giza for example)
has 4 triangle sides and one square side (the bottom / base)
it has 4 bottom points (vertices) + 1 top one.
its edges are 4 on the bottom and 4 going up from the the corners to the top
when put together base to base the bases disappear (no longer outside but internal to the pyramid and therefore don't count.
2 four sides become your 8 sides
the four bottom points on one pyramid merge into the others giving you only 4 base points plus your 2 "top" points.
total of 6 vertices
edges you have the 4 base edges plus 4 from each corner going up and 4 going down to the "top" points
that make 12.
