Vertex · A vertex is the sharp corner where edges come together.
12 · 4 around top, 4 around bottom, 4 joining: 12.
8 · Top 4 plus bottom 4: 8.
Face · A face is the flat part you can touch, like the side of a box.
True · Right: 6, 12, 8.
face · Flat surfaces are faces.
6 · Three pairs: 6.
5 · Add the triangle faces and rectangle faces: 2 plus 3 makes 5.
She swapped the numbers for faces and edges · A cube has 6 faces and 12 edges, not the other way around.
True · Right: faces meet at edges.
