Question 1 of 10
1. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X).
Correct
Answer: Option C
Explanation:
The fig. (X) is similar to the Form VI. So, when a cube is formed by folding the sheet shown in fig. (X), then is one of the faces of the cube. However, the cube in fig. (1) has two such faces and fig. (4) has a face which is completely shaded. So, these two cubes cannot be formed. Hence, only the cubes in figures (2) and (3) can be formed.Incorrect

Question 2 of 10
2. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X). Correct
Answer: Option A
Explanation:
The fig. (X) is similar to the Form I. So, when the sheet shown in fig. (X) is folded to form a cube then one of the two halfshaded faces lies opposite to one of the blank faces and the other halfshaded face lies opposite to another blank face. The two remaining blank faces lie opposite to each other. Thus, both the cubes shown in figures (1).and (4) can be formed when the sheet shown in fig. (X) is folded. Also, though the cubes shown in figures (2) and (3) have faces that can appear adjacent to each other but the cube formed by folding the sheet in fig. (X) cannot be rotated to form either of the two. Hence, the cubes in figures (2) and (3) cannot be formed.Incorrect

3. Question
1 pointsHow many dots lie opposite to the face having three dots, when the given figure is folded to form a cube?
Correct
Answer: Option D
Explanation:
The given figure is similar to Form V. Therefore, when this figure is folded to form a cube then the face bearing six dots will lie opposite the face bearing three dots.Incorrect
Answer: Option D
Explanation:
The given figure is similar to Form V. Therefore, when this figure is folded to form a cube then the face bearing six dots will lie opposite the face bearing three dots. 
Question 4 of 10
4. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X).
Correct
Answer: Option A
Explanation:
The fig. (X) is similar to Form II. So, when the sheet shown in fig. (X) is folded to form a cube then the two halfshaded faces lie opposite to each other, the face bearing a circle lies opposite to one of the two blank faces and the two remaining blank faces lie opposite to each other. Therefore, the cubes shown in fig. (4) which has the two halfshaded faces adjacent to each other, cannot be formed by folding the sheet shown in fig. (X). Also, the cube shown in fig. (2) has the face bearing a circle adjacent to two blank faces. This is not possible since there is one blank face opposite to the circle and one blank face opposite to the third blank face. Hence, only the cubes in figures (1) and (3) can be formed.Incorrect
Answer: Option A

The fig. (X) is similar to Form II. So, when the sheet shown in fig. (X) is folded to form a cube then the two halfshaded faces lie opposite to each other, the face bearing a circle lies opposite to one of the two blank faces and the two remaining blank faces lie opposite to each other. Therefore, the cubes shown in fig. (4) which has the two halfshaded faces adjacent to each other, cannot be formed by folding the sheet shown in fig. (X). Also, the cube shown in fig. (2) has the face bearing a circle adjacent to two blank faces. This is not possible since there is one blank face opposite to the circle and one blank face opposite to the third blank face. Hence, only the cubes in figures (1) and (3) can be formed.

5. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X). Correct
Answer: Option D
Explanation:
The fig. (X) is similar to Form II. So, when a cube is formed by folding the sheet shown in fig. (X), then the two halfshaded faces lie opposite to each other and one. of the three blank faces appears opposite to the face bearing a dot. Clearly, each one of the four cubes shown in figures (1), (2), (3) and (4) can be formed by folding the sheet shown in fig. (X).Incorrect
Answer: Option D
Explanation:
The fig. (X) is similar to Form II. So, when a cube is formed by folding the sheet shown in fig.

Question 6 of 10
6. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X). Correct
Answer: Option C
Explanation:
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.Incorrect
Answer: Option C
Explanation:
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. 
Question 7 of 10
7. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X). Correct
Answer: Option B
Explanation:
The fig. (X) is similar to the Form III. So, when the sheet in fig. (X) is folded to form a cube, then ‘F’ appears opposite ‘B’, ‘E’ appears opposite ‘C’ and ‘A’ appears opposite ‘D’ Therefore, the cube in fig. (1) which shows ‘F’ adjacent to ‘B’ the cube in fig. (3) which shows ‘E’ adjacent to ‘C’ and the cube in fig. (4) which shows ‘A’ adjacent to ‘D’ cannot be formed. Hence, only the cube in fig.(2) can be formed.Incorrect
Answer: Option B
Explanation:
The fig. (X) is similar to the Form III. So, when the sheet in fig. (X) is folded to form a cube, then ‘F’ appears opposite ‘B’, ‘E’ appears opposite ‘C’ and ‘A’ appears opposite ‘D’ Therefore, the cube in fig. (1) which shows ‘F’ adjacent to ‘B’ the cube in fig. (3) which shows ‘E’ adjacent to ‘C’ and the cube in fig. (4) which shows ‘A’ adjacent to ‘D’ cannot be formed. Hence, only the cube in fig.(2) can be formed. 
Question 8 of 10
8. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X). Correct
Answer: Option B
Explanation:
The fig. (X) is similar to the Form III. So, when the sheet in fig. (X) is folded to form a cube, then the halfshaded face appears opposite to the face bearing a rhombus, the face with a black circle appears opposite to one of the two blank faces and the face with a ‘+’ sign appears opposite to the other blank face. Clearly, the cubes shown in figures (1) and (4) cannot be formed since they have the halfshaded face adjacent to the face bearing the rhombus. Also, though the cube shown in fig. (3) has faces that can appear adjacent to each other but the cube formed by folding the sheet in fig. (X) cannot be rotated to form fig. (3). Hence, the cube in fig. (3) cannot be formed. Thus, only the cube shown in fig. (2) can be formed.Incorrect

9. Question
1 pointsChoose the box that is similar to the box formed from the given sheet of paper (X).
Correct
Answer: Option A
Explanation:
The fig. (X) is similar to the Form II. So, when the sheet shown in fig. (X) is folded to form a cube then the two halfshaded faces lie opposite to each other, the face bearing a square lies opposite to one of the two blank faces and the face bearing a circle lies opposite to the other blank face. Therefore, the cubes shown in figures (2) and (3) which have the two halfshaded faces adjacent to each other, cannot be formed by folding the sheet shown in fig. (X). Also, though the cube shown in fig. (4) has faces that can appear adjacent to each other but the cube formed by folding the sheet in fig. (X) cannot be rotated to form the cube in fig. (4). Hence, only the cube in fig. (1) can be formed.Incorrect
Answer: Option A

The fig. (X) is similar to the Form II. So, when the sheet shown in fig. (X) is folded to form a cube then the two halfshaded faces lie opposite to each other, the face bearing a square lies opposite to one of the two blank faces and the face bearing a circle lies opposite to the other blank face. Therefore, the cubes shown in figures (2) and (3) which have the two halfshaded faces adjacent to each other, cannot be formed by folding the sheet shown in fig. (X). Also, though the cube shown in fig. (4) has faces that can appear adjacent to each other but the cube formed by folding the sheet in fig. (X) cannot be rotated to form the cube in fig. (4). Hence, only the cube in fig. (1) can be formed.
