If the following figure is folded from the intersection of common edges to make dice, then how many dots will be on the face opposite to the face having 1 dot?
Correct Answer : d ) 3Explanation :
These types of questions can be solved using the logic given below:
- In the 2D question figure if there are two faces or squares in a straight line, then the two faces will never be opposite to each other in the final 3D cube.
- In the 2D question figure, if there are more than 2 faces or squares in a straight line, then the faces or squares at a gap of one block in the straight line will always be opposite to each other.
Now, considering the given figure:
In straight-line 1, face having 4 dots and face having 2 dots are at a gap of one face so, they will be opposite to each other.
In straight-line 2, face having 6 dots and face having 5 dots are at a gap of one face so, they will be opposite to each other.
Therefore, the remaining faces, i.e. face having 1 dot and face having 3 dots, will be opposite to each other.
Hence, (d) is the correct answer.
