Conversion between meters and centimeters:
To understand how many centimeters make 3 meters, we need to know the conversion between meters and centimeters.

1 meter is equal to 100 centimeters. This means that if we have 1 meter, we can multiply it by 100 to get the equivalent length in centimeters.

Calculating the length in centimeters:
To find out how many centimeters make 3 meters, we can use the conversion factor mentioned above.

3 meters multiplied by 100 centimeters/meter gives us the length in centimeters.

3 meters * 100 centimeters/meter = 300 centimeters

So, 3 meters is equal to 300 centimeters.

Explanation of the correct answer:
The correct answer is option C, which states that 300 centimeters make 3 meters. This is the correct answer because the conversion factor between meters and centimeters is 100. Therefore, 3 meters can be converted to 300 centimeters by multiplying 3 by 100.

Summary:
- 1 meter is equal to 100 centimeters.
- To convert meters to centimeters, we multiply the length in meters by 100.
- 3 meters multiplied by 100 centimeters/meter gives us the length in centimeters.
- Therefore, 3 meters is equal to 300 centimeters.
