Dice are cubes with dots or dots on the face. Opposite faces of a die always have a total of seven on them.
In the given below net to make dice (cube), the numbers inserted in the square indicate the number of dots in it.

Insert suitable numbers in the blank so that numbers in opposite faces of the die have a total of seven dots.
