One die is drawn below in two different ways. Find the number opposite 3.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 2
A face of a die touches four other faces and is opposite the one face it never touches. Faces seen together in one picture are neighbours, so they can never be opposite each other.
3 is seen next to 4 and 5 in (i); 1 and 6 in (ii). So 3 touches four faces, and the only face left, 2, is opposite 3
Why the other options are incorrect
Option (1) 5 — Incorrect. 5 is seen next to 3 in picture (i), so it touches 3 and cannot be opposite it.
Option (2) 1 — Incorrect. 1 is seen next to 3 in picture (ii), so it touches 3 and cannot be opposite it.
Option (4) 6 — Incorrect. 6 is seen next to 3 in picture (ii), so it touches 3 and cannot be opposite it.
