alleryA cube's corner cut meets only its 3 incident edges. Changes (faces, vertices, edges)?
A+1, +3, +3
B+1, +2, +2
C−1, +2, +3
D+1, +2, +3
Answer & Solution
Correct answer: D. +1, +2, +3
The cut adds one triangular face, replaces one vertex by three, and adds three edges, giving changes of +1, +2 and +3.
