Explanation: A standard six-sided die is a common object used in various games and probability problems. Each face of the die is marked with a number of dots ranging from 1 to 6. The numbers on the faces are arranged such that the sum of the numbers on opposite faces is always 7. For example, the face with 1 dot is opposite the face with 6 dots, the face with 2 dots is opposite the face with 5 dots, and the face with 3 dots is opposite the face with 4 dots.
To find the total number of dots on a die, we need to sum the numbers on all six faces. The numbers on the faces are 1, 2, 3, 4, 5, and 6. The sum of these numbers can be calculated as follows:
\[ 1 + 2 + 3 + 4 + 5 + 6 \]
We can add these numbers step by step:
\[ 1 + 2 = 3 \]
\[ 3 + 3 = 6 \]
\[ 6 + 4 = 10 \]
\[ 10 + 5 = 15 \]
\[ 15 + 6 = 21 \]
Thus, the total number of dots on a die is 21. This sum is a fixed value and is a fundamental property of a standard six-sided die. Understanding this concept is important for various applications in probability, games, and general knowledge.
It is important to note that the sum of the numbers on opposite faces of a die is always 7. This property can be used to verify the arrangement of the numbers on the faces of the die. For example, if the face with 1 dot is opposite the face with 6 dots, the sum is 7. Similarly, the face with 2 dots is opposite the face with 5 dots, and the face with 3 dots is opposite the face with 4 dots, each pair summing to 7.
In summary, the total number of dots on a standard six-sided die is 21, which is the sum of the numbers 1 through 6. This concept is a basic but important piece of general knowledge and is often tested in various competitive examinations in India.
