Answers
Given :- all cubes below have a different image on each side. select the choice that represents a rotation of the cube labeled X.
Solution :-
In cube X :-
- 2 dot lines = Let denoted by 2 .
- 3 dot lines = Let denoted by 3 .
- 4 dot lines = Let denoted by 4 .
now, checking given options .
A) when we rotate X 90° clockwise we get,
- 4 on right face .
- 2 goes at down face .
- since in (A) both 2 and 4 are given . so, it is not possible .
B) Rotating X 90° anticlockwise we get,
- 2 = Top face .
- 4 = Left face and not visible .
- 3 = Right face .
- then, (B) is possible.
C) As we can see that, 3 is at same position and rest two changes , then, this cube is also not possible .
E) when we rotate clockwise or anticlockwise 2,3 and 4 will not be visible together again .
F) when we rotate 2 , 90° clockwise .
- 2 = front face .
- 3 = left face = not visible .
- 4 = visible .
- since 4 is not visible in (E) , this rotation is not possible.
G) when we rotate clockwise or anticlockwise 2,3 and 4 will not be visible together again .
therefore, we can conclude that, only (B) cube is possible when we rotate cube X .
