Text Solution

What is known?

A net.

What is unknown?

Can this be a net for a dice.

Reasoning:

Dice is a cube with dots on each face. Opposite faces of a die always have a total of seven dots on them. Make a cube of this net and if opposite faces of this cube have sum of \(7\) then it can be a net for dice.

Steps:

No, because we know that dice is a cube with dots on each face. Opposite faces of a die always have a total of seven dots on them.

So, if we will fold this net opposite to \(4\) will be \(1\) and opposite to \(3\) will be \(6\) which does not make total of \(7.\)
