Subtopic: Opposite face in unfolded cube net

Question Statement:

Suppose the faces of the cube are renumbered with distinct prime numbers such that opposite faces sum to 24. If Face 1 has value 5, determine the value on Face 3 (enter the integer value).

Answer Key:

19

Step-by-Step Solution & Explanation

Face 1 and Face 3 are opposite. Since their sum is 24 and Face 1 is 5, Face 3 must be $24 - 5 = 19$ (which is a prime).
