It's ambiguous. I've done graduate work in mathematics. The answer could be 2 faces, 5 vertices, 5 edges (counting vertices where the line clearly changes direction) or 2,2,2 (counting only vertices where three edges meet) or or 5,6,9 (extrapolating the figure to a triangular prism). I expect the teacher wanted either the first or third answer, but I don't know. Who wrote this? And what's the point? Learning names is not mathematics and it's a waste of time. Most scholastic math terms are never used by adults. A few examples: "whole number", "improper fraction", "mixed fraction", "complementary angles", "supplementary angles". And all that stuff in algebra class about conic sections and X and Y intercepts etc. is a complete waste of time. The interesting thing is that V + F - E = 2.
@exitseven Oh no. Don't faint. I'll revive you by talking to you about e, or pi, or phi (Golden Ratio). Do you know about Vesica Piscis? That's interesting too. Then there's the n-body problem (gravitational attraction). Anyway, 'The Cube' is a good film. I thought so anyway (I've got the DVD).
