Non Verbal Reasoning - Cubes and Dice - Discussion

The sheet of paper shown in the figure (X) given on the left hand side, in each problem, is folded to form a box. Choose from amongst the alternatives (1), (2), (3) and (4), the boxes that are similar to the box that will be formed.


Choose the box that is similar to the box formed from the given sheet of paper (X).

[A]. 1 only
[B]. 1 and 3 only
[C]. 1, 3 and 4 only
[D]. 1, 2, 3 and 4

Answer: Option C


When the sheet in fig. (X) is folded, then one of the faces of the cube formed will be of the form and this face will lie opposite the face bearing a square. Also, one of the blank faces lies opposite another blank face and the third blank face lies opposite the face bearing an '=' sign. Clearly, all the three blank faces cannot appear adjacent to each other. So, the cube shown in fig. (2) which has all the three blank faces adjacent to each other cannot be formed. Hence, only the cubes shown in figures A, C and D can be formed.

Surfaces which are connected to the surface containing square are three plain surfaces and one surface that is containing equal sign. So here we can see three plane surfaces also. Any one of which is not opposite to each other so we can also find fig 2 by this way. Kindly guide.

All the 4 options can be made, 2 figure is possible, by keep the centre square down towards ground, and the 3 viewing faces will be plain/white.

According to figure, two plain surfaces must be opposite to each other, but in option 2 plain surface is not opposite so option 2 can't be formed.
