In the Cube and Dice logical reasoning section, A cube is a three dimensional solid object bounded by six square faces or surfaces, it can also be called a “regular hexahedron”. We are often interested in finding its surface area and volume. On the other hand, dice are cubical or cuboidal shape objects containing numbers/figures/symbols embedded on their surfaces. Dice are used for gambling and non gambling such as craps, ludo etc.

Several types of questions based on Cube and Dice reasoning are asked regularly in various competitive examinations. In this article, we are going to cover the key concepts of the Cube and Dice reasoning section along with the solved examples, practice questions and the tips and tricks etc. Read the article thoroughly to clear all the doubts regarding the same.

**What is Cube and Dice?**

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.

## Important Facts

- A cube has 6 square faces or sides
- A cube has 8 points (vertices)
- A cube has 12 edges
- Only 3 sides of a cube are visible at a time (known as “Joint Sides”) and these sides can never be on the opposite side of each other
- Things that are shaped like a cube are often referred to as ‘cubic’
- Most dice are cube shaped, with the numbers 1 to 6 on the different faces.

**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.

**Problem based on Single Dice **

In this type of cube and dice reasoning, problems related to single dice will be given.

**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.

## Basic Rules for Dice

There are certain dice rules in reasoning which can be used to solve dice-based questions:

### Rule No. 1:

Two opposite faces of the dice cannot be adjacent to each other.

Here, faces with number 4, 3, 6 and 1 are adjacent to the face number 2.

Therefore, the 4, 3, 6, 1 can’t be opposite to the face number 2.

Therefore, face number 5 is opposite to face number 2.

### Rule No. 2:

If two dice are as shown below, and one of the two common faces (Face number 4) is in the same position, then the remaining faces will be opposite to each other.

In both the diagrams, two faces numbered 1 & 3 are common.

Also, 5 & 6 are remaining faces. Hence, the face which is number 5 is opposite to the face number 6.

### Rule No. 3:

If in 2 different positions of the dice, the positions (different), the position of the face that’s common is the same, and then the opposite faces of the faces that remain will be in the same positions.

### Rule No. 4:

If 2 positions of a die are given (Different) and it is also stated that the common face is different then the face opposite to the given common face would be that which is not shown on any given face in the 2 given positions. It is also to be noted that the opposite face of the faces that are left cannot be the same.

Note, in the above shown dice, the face having value 6 is not in the similar position.

The face numbered 1 is not shown.

So, the face opposite to the face with number 6 is 1. Also, the opposite face of 3 is the face with number 2 and the opposite to face numbered 5 is the face with number 1.
