If a cube is painted on all of its surfaces with acolour and then divided into smaller cubes of equalsize then after separation, number of smaller cubesso obtained will be calculated as under :Number of smaller cubes with three surfacespainted = 8Number of smaller cubes with two surfacespainted = (n � 2) × 12

Number of smaller cubes with one surfacespainted = (n � 2)2 × 6

Number of smaller cubes with no surfaces painted= (n � 2)3

TYPE III

If a cube is painted on its surfaces in such a waythat one pair of opposite surfaces is left unpainted.

Directions : ( 8 to 11 ) A cube of side 4 cm is painted red onthe pair of one opposite surfaces, green on thepair of another opposite surfaces and one pair ofopposite surfaces is left unpainted. Now the cubeis divided into 64 smaller cubes of side 1 cm each.

Ex 8. How many smaller cubes have three surfacespainted ?(A) 0 (B) 8(C) 16 (D) 20

Sol. (A) Number of smaller cubes with three surfacespainted = 0 (Because each smaller cube at thecorner is attached to a surface which is unpainted.)

Sol. (A) Number of smaller cubes with three surfacespainted = Number of smaller cubes at two corners= 2

Ex 13. How many smaller cubes have two surfacespainted ?(A) 4 (B) 8(C) 16 (D) 14

Sol. (D) Number of smaller cubes with two surfacespainted = Number of smaller cubes at four corners+ Number of smaller cubes at 5 edges.= 4 + (n � 2) × 5 = 4 + 2 × 5

DICES

Type-I

General Dice : In a general dice the sum of numberson the any two adjacent faces is �7�.Standard Dice : In a standard dice the sum ofnumbers on the opposite faces is '7'.

Ex 16. Which number is opposite 4 in a standard dicegiven below ?

41

5

(A) 1 (B) 3(C) 5 (D) Can�t be determined

Sol. Clearly , from the standard dice the sum ofnumbers on the opposite faces is '7', so numberopposite to 4 is 3.

Type-II

Ex 17. The figures given below show the two differentpositions of a dice. Which number will appearopposite to number 2 ?.

(A) 3 (B) 4(C) 5 (D) 6

Sol. (C) The above question,where only two positions ofa dice are given, can easilybe solved with thefollowing method.

Step I. The dice, when unfolded, will appear as shown inthe figure given on the right side.

Step II. Write the common number to both the dice in themiddle block. Since common number is 4, hencenumber 4 will appear in the central block.

Step III. Consider the figure (i) and write the first number inthe anti-clockwise direction of number 4,(common number) in block I and second numberin block II. Therefore, numbers 3 and 2 being thefirst and second number to 4 in anticlockwisedirections respectively, will appear in block I & IIrespectively.

Step IV. Consider figure (ii) and wire first and secondnumber in the anticlock-wise direction to number4, (common number) in block (III) & (IV). Hencenumbers 6 and 5 will appear in the blocks III and IVrespectively.

Step V. Write remaining number in the remaining block.Therefore, number 1 will come in the remainingblock. Now, from the unfolded figures we find thatnumber opposite to 6 is 3, number opposite to 2 is5 and number opposite to 4 is 1. Therefore, option(C) is our answer.( Short Trick : From the given dice, we will take thecommon number as the base and then in itsrespect move clockwise direction and write asfollows : 4 � 2 � 3

4 � 5 � 6.Here,we find that number opposite to 6 is 3, numberopposite to 2 is 5 and number opposite to 4 isremaining number 1.Therefore, option (C) is our answer. )

Ex 18. On the basis of two figures of dice, you have to tellwhat number will be on the opposite face of number5 ?

(A) 1 (B) 2(C) 4 (D) 6

Page 4: CUBE AND DICE-TEST · corners, 6 surfaces and 12 edges. If a cube is painted on all of its surfaces with any colour and further divided into various smaller cubes, we get following

PAGE # 92

Sol. (D) The above question where only two positionsof a dice are given, can easily be solved with thefollowing method :If in the given dice, there are two numbers common,then uncommon numbers will always be oppositeof each other.Therefore, option (D) is our answer.

Type-III

Ex 19. From the following figures of dice, find whichnumber will come in place of �?�

(A) 4 (B) 5(C) 2 (D) 3

Sol. (D) If the above dice is unfolded, it will look like asthe figure (i) given below.

Figure (i)

Now the number in place of �?� can be obtained by

making a slight change in the figure as given here.Now comparing figure (ii) with third dice as above,we get that number in place of ? is 3.

Figure (ii)

Type-IV

Ex 20. A dice has been thrown four times and producesfollowing results.

Which number will appear opposite to the number3 ?(A) 4 (B) 5(C) 6 (D) 1

Sol. (A) From the figures (i), (ii) and (iv) we find thatnumbers 6, 1, 5 and 2 appear on the adjacentsurfaces to the number 3. Therefore, number 4will be opposite to number 3.

Type-V

Ex 21. Which of the following dices is identical to theunfolded figure as shown here ?

(X)

(A) (B)

(C) (D)

Sol. (A) From the unfolded figure of dice, we find thatnumber opposite to 2 is 4, for 5 it is 3 and for 1 it is6. From this result we can definitely say that figure(B), (C) and (D) can not be the answer figure asnumbers lying on the opposite pair of surfaces arepresent on the adjacent surfaces.
