Question

Can this be a net for a die?

Explain you answer

Solution

The given net can be folded as follows.

It can be observed that the opposite faces of the dice so formed have 2 and 5, 1 and 4, 3 and 6 on them. The sum of the numbers on the opposite faces comes to 7, 5, 9 respectively. However, in case of a dice, the sum of the numbers on the opposite faces should be 7. Hence, this net is not of a dice.

  Is there an error in this question or solution?
