Two different positions of the same dice are shown. Select the number that will be on the face opposite to that of number 5.

3 is common to both views. Going round face 3 in the same rotational sense, the first die shows 4 then 6 and the second 5 then 1, so the four faces round 3 are 4, 6, 5, 1 in order. Opposite faces are 4–5 and 6–1, so 4 is opposite 5.
