As mentioned above, Cube is a three dimensional figure which can only be made out of square. Square when given a height equal to one of the sides, becomes a cube. Die/Dice is a three dimensional figure with each of its six sides/faces showing different numbers/letters/colours etc. It has 8 corners and 12 edges. In a dice, length, breadth and height all are equal to each other.
Several types of problems based on Cube and Dice reasoning sections are asked in various government competitive exams, some of them are given below.
Types of Cube and Dice Reasoning
As now we know what consists of the questions related to the Cube and Dice reasoning section. Let us see the various types of questions that may come one by one from below.
1. Problem based on Single Dice
In this type of cube and dice reasoning, problems related to single dice will be given.
2. Problem based on Two or more Dice
In this type of cube and dice reasoning, problems related to two or more that two dice will be given.
How to Solve Question Based on Cube and Dice – Know all Tips and Tricks
Candidates can find various tips and tricks from below for solving the questions related to the Cube and Dice reasoning section.
Tip # 1: In a cube we find Length = width = height. Altogether there are six surfaces, twelve edges and eight corners
Tip # 2: Cuboid = in a cuboid length and breadth is not as same as its height.
Tip # 3: Types of dice are Ordinary Dice and Standard Dice
Tip # 4: It is a regular cube with its six sides numbered with dots from 1 to 6 with opposite sides adding up to 7.
Tip # 5: In standard dice, always “6 is opposite to 1”, “5 is opposite to 2” and “4 is opposite to 3”.
Tip # 6: In ordinary dice, Sum of any two number of the adjacent surface is = 7
Cube and Dice Reasoning Sample Questions
Question 1: What number will be opposite to 2?
Solution: It is a standard dice as no of any adjacent sides are 7. As, standard dice, opposite no. of 2 will be
6 ↔ 1
5 ↔ 2
4 ↔ 3
Ans is 5, (sum of opposite side is 7)
Question 2: What no will be opposite to 4?
Solution: It is an ordinary dice as the sum of right and left side is 7. So, opposite no. of 4 can be – 1, 3 or 6.
So, the answer is → can’t be determined.
Question 3: What no will be opposite to 3?
Solution: We have to check the possibility.
Here, the no of dice is1, 2, 3, 4, 5, 6 As per above diagram 3, 2 and 4. Can’t be any of the opposite faces of 2.
So, there are all eliminated only 1, 5 or 6 are possible numbers of opposite faces of 3.
Then option b is correct i.e. 1/5/6.

Question 4: What is the example of a standard dice?
Solution: As per definition of standard dice, any of the two opposite faces of dice must be 7.
So, only in dice A the sum of two adjacent faces is 7.
Hence, the correct answer is A.
Question 5: What is the opposite face of “Red”?
Solution: Blue is common in both dices, so putting blue as a constant term we have to rotate two dices by clockwise and anticlockwise direction, so we get the opposite side of red is yellow.
Hence, the correct answer is yellow.
