21 inches into cm if cm is =2.5 show working
To convert inches to centimeters, you can use the conversion factor:
1 inch = 2.54 centimeters
So, to convert 21 inches into centimeters:
21 inches * 2.54 cm/inch = 53.34 cm
If cm is actually 2.5, we can check this by using the same conversion factor:
21 inches * 2.54 cm/inch = 53.34 cm
Since 53.34 cm is not equal to 2.5 cm, it seems there was a mistake in the given information.
