a. 0

b. 2

c. 4

d. 6

Directions for questions 7 to 10: The following questions are based on the information given below:

1. There is a cuboid whose dimensions are 4 x 3 x 3 cm.

2. The opposite faces of dimensions 4 x 3 are coloured yellow.

3. The opposite faces of other dimensions 4 x 3 are coloured red.

4. The opposite faces of dimensions 3 x 3 are coloured green.

5. Now the cuboid is cut into small cubes of side 1 cm.

7. How many small cubes will have only two faces coloured?

a. 12

b. 24

c.  16

d. 14

8. How many small cubes have three faces coloured ?

a. 24

b. 20

c. 16

d. 8

9. How many small cubes will have no face coloured?

a. 1

b. 2

c. 4

d. 8

10. How many small cubes will have only one face coloured?

a. 10

b. 12

c. 14

d. 18

1. Option (d). Exp: In first two positions of dice one common face containing 5 is same. Therefore
according to rule no. (3) the face opposite to the face which contains 2 point, will contains 6 points.

2. Option (a). Exp: The colours adjacent to yellow are orange, blue, red and rose. Hence violet will be
opposite to yellow.

3. Option (c). Exp: According to the rule no. (3), common faces with number 3, are in same positions.
Hence the number of the opposite face to face with number 5 will be 6.

4. Option (c). Exp:  Even numbered dice are: (II), (IV) and (VI)

No. of dots on the top face of (II) dice = 6

No. of dots on the top face of (IV) dice = 6

and No. of dots on the top face of (VI) dice = 6

Therefore Required total = 6 + 6 + 6 = 18

5. Option (a). Exp: Odd numbered dice are : (II), (III) and (V)

No. of dots on the top faces of these dice are 2, 2 and 4 respectively.

Required total = 2 + 2 + 4 = 8

6. Option(d). Exp: No. of faces on the top faces of the dice (I), (II) and (III) are 5, 1 and 5 respectively.

Therefore, Total of these numbers = 5 + 1 + 5 = 11

No. of dots on the top faces of the dice (IV), (V) and (VI) are 1, 3 and 1 respectively.

Therefore, Total of these numbers = 1 + 3 + 1 = 5

Required difference = 11 - 5 = 6.

7. Option (c). Exp: Number of small cubes having only two faces coloured = 6 from the front + 6 from the back + 2 from
the left + 2 from the right = 16.

8. Optin (d). Exp: Such cubes are related to the corners of the cuboid and there are 8 corners.

Hence, the required number is 8.

9. Option (b). Exp: Number of small cubes have no face coloured = (4 - 2) x (3 - 2) = 2 x 1 = 2.

10. Option (a). Exp: Number of small cubes having only one face coloured = 2 x 2 + 2 x 2 + 2 x 1

= 4 + 4 + 2

= 10

Cubes and dices appear in competitive exams like railways, IBPO, CAT, CMAT, bank po etc. For cubes and dices questions the candidates should be able to imagine the 3-D figures with the help of 2-D description and blueprint. These types of questions put stress on your mind, but it will be a lot easier when you have developed that particular skill of visualizing figures through the visual bent of your mind. Freshersworld provides students or job seekers with the tricks and tips, cubes and dices problems with solutions and practice questions. What is difference between cube and dice? A cube is a geometric shape -- a hexahedron -- in which there are 6 square faces. Dice are polyhedral objects used as random number generators. What number must be added to the set 6, 16 and 8 to get an average of 13? 22 must be added to 6, 16, and 8 to get an average of 13.
