Top question on the first page.

Ans: Dice net D

Explanation:

Since the opposite sides needs to sum to 7, the net requires the opposite faces to add up to 7.

In net D, notice the side with 4 dots. You need the opposite side of 4, so you go up by two and the side opposite to 4 is 3 dots.

4 + 3 = 7

The same thing goes for side 2. Go up by two faces and you see the 5 dots side.

2 + 5 = 7

1 dot side and 6 dot side add up to 7.

This net is proven to have opposite sides to sum up to 7.
