Explanation:
Validate with given positions:
The first position has numbers 1, 4, and 3.
The second position has numbers 1, 3, and 2.
The third position has numbers 1, 2, and 6.
By analyzing these positions, we confirm that 5 is not adjacent to 1 in any of the given positions, implying that 5 is on the opposite face of 1.
Thus, the number on the face opposite to the face showing '5' is 1.
