Question

Which of the following nets is the net of a regular die?

• A.
• B.
• C.

Answer 1

The correct option is B

Solution:

In a regular die, the sum of the digits on the opposite faces is seven.
In option A, 5 and 2 are adjacent, thus it is not a correct net.
In option B, when all faces will be folded, 1 will be opposite to 6, 2 will be opposite to 5, and 3 will be opposite to 4. Thus, the sum of digits on all the opposite faces will be 7, and this will be a correct net for a regular die.
In option C, 5 is opposite to 1, thus it is not a correct net, as the sum of digits on opposite faces should be 7 for a regular die.
Hence, option B is the correct net of a regular die.
