Question

Dice are cubes with dots on each face. Opposite faces of a die always have a total of seven dots on them.
Here are two nets to make dice(cubes); the numbers inserted in each square indicate the number of dots in that box.
Insert suitable numbers in the blanks, remembering that the number on the opposite faces should total to $7$.

Answer 1

First Net :
Since, the number left to 4 will be opposite to 5, it should be 2.
The number left to 2, will be opposite to 4, it will be 3. 1 will be put in left over face, which will come to opposite of 6.
Second Net :
When folded, 6 comes opposite to 1, 4 comes opposite to 3, and 5 comes opposite to 2.
