Ananyaa rolls an ordinary dice and gets the number 2 on the face of the dice. What shall be the square of the number that lies exactly opposite on the dice to the number that Ananyaa got on the face of the dice?

The question asks: Ananyaa rolled a $2$, what is the square of the number on the opposite face?

---

On a standard dice, opposite faces always add up to $7$.

This means:

• $1$ is opposite to $6$ (because $1 + 6 = 7$)
• $2$ is opposite to $5$ (because $2 + 5 = 7$)
• $3$ is opposite to $4$ (because $3 + 4 = 7$)

---

Ananyaa rolled a $2$.

Using the rule that opposite faces sum to $7$:

Opposite number $= 7 - 2 = 5$

---

The question asks for the square of the opposite number.

The opposite number is $5$.

Square $= 5 \times 5 = 25$

---

Therefore, the answer is $25$.

Pro Tip: Whenever you see a dice problem, remember: Opposite number $= 7 -$ Given number. This works for all standard dice!
