What is a Dice?
A dice is small cube which has sides with different number printed on them.
 
Types of Dice:
Base Dice
Open Dice
 
The Base Dice has two Type :
1. Standard Dice
2. Ordinary Dice
 
 
What is Standard dice?
If a two dices no number are match each other then it is a standard dice.

Cubes and Dice

Both dices having number are not matching So we can call it standard dice.
 
 
What is Ordinary Dice?
If a number of two dice are matched, then it is called an ordinary dice.

Cubes and Dice

Here we see the two dices, In first one having number 2,3,4 and the second dice having number 3,5,6. Here we say the number 3 are matched. So it is a Ordinary dice.
 
 
Rule 1:
If there is one element is common in both dices also having the same surface then the remaining surface of both dice opposite to each other.

Cubes and Dice
Here are two dices and both the dices having number 4 which has same surface. So according to the rule if both dices also having the same surface and also similar number then the remaining surface of both dice 3,5 and 1,2 are opposite to each other. we can say according to rule 2 is opposite to 5 and 1 is opposite to 3.
 
Rule 2:
If two numbers are same in both dices whether there surface are no equal, then the remaining number of both dice are opposite to each other.

Cubes and Dice
Here we see that there are two dices and In this dices 6,2 are similar but you can see that 3, 5 are dissimilar.  It means 5,3 are opposite to each other, If ask about the opposite of 2 and 6 then the answer is can’t be determine because 2 & 6 are similar in both so there are no possible to determine.
 
Rule 3:
If there is one element common in both the dices having different surface then rotate it in clockwise direction to find out the opposite surface.

Cubes and Dice
According to this rule there are two dices as we see 2 is common in both the dices but there surface are different so to find out the opposite of  5  & 6, we need to do some steps. At first we  do mark similar common number in both the dices then rotate in clock wise direction.
As we see after rotating it in clockwise direction first 6 is appear then 5 is appear. So, 6 is opposite to 4.
In second dices after rotating in clockwise direction 4 is appear first then 1 is appear. So, 5 is opposite to 1.
Note : After rotating in clockwise direction  6 & 4 become first appearance So these are opposite to each other. 5 & 1 are appear in second one So, these one opposite each other.
 
 
Open Dice
Cubes and Dice
Rule 1:
E & F are always opposite to each other and any type of open dice whether it is B & F, B & F OR c & D etc. These to surfaces are always opposite to each other.
Rule 2:
These two A & C there surfaces are not touches each other so, there are opposite to each other.
Rule 3:
Here we see B & D are not touching each other surfaces So, B & D opposite to each other.
E opposite to F
A opposite to C
B opposite to D
