To convert 8 inches to centimeters, first we need to understand the relationship between these two units of length. 1 inch is equal to 2.54 centimeters, which means that there are 2.54 centimeters in every inch.
Now, to convert 8 inches to centimeters, we can use a simple formula:
Centimeters = Inches x 2.54
So, to convert 8 inches to centimeters, we just need to plug in the value of 8 for inches in the formula above:
Centimeters = 8 x 2.54
= 20.32 cm (rounded to two decimal places)
Therefore, 8 inches is equal to 20.32 centimeters.
Alternatively, we can also use unit cancellation to convert inches to centimeters. This method involves setting up a proportion, where we know that 1 inch is equal to 2.54 centimeters.
So, the proportion would be:
1 inch / 2.54 centimeters = 8 inches / x centimeters
To find the value of x (in centimeters), we can cross multiply:
1 inch * x centimeters = 8 inches * 2.54 centimeters
x = (8 * 2.54) / 1
= 20.32 cm (rounded to two decimal places)
Therefore, again, we get the same value of 20.32 centimeters.
In conclusion, to convert 8 inches to centimeters, we can either use a simple formula or set up a proportion and use unit cancellation. Both methods will give us the same result of 20.32 centimeters.
