Question

One inch is equivalent to 2.54 centimeter. How many centimeters are in two feet? Round off your answer to two decimal places.

Answer 1

Hint: Before solving this question, we must know the following conversions:-
1 Inch = 2.54 centimeter
1 foot = 12 inches

Complete step-by-step answer:
We know that 1 foot is equal to 12 inches and 1 inch is equal to 2.54 centimeters.
Therefore, 1 foot = \[12\times 2.54\] centimeter
 Hence, 1 foot = 30.48 centimeter

Now, we need to find out how many centimeters there are in 2 feet. For that, we will multiply 2 by 30.48.
2 feet = 60.960 centimeter

Now, rounding off 60.960 centimeter to two decimal places, we get 60.96 centimeter.
Therefore, the answer to this question is 60.96 centimeter, i.e. 2 feet is equal to 60.96 centimeter.

Note: The student must know about Rounding Off numbers. Here is a definition for Rounding Off numbers:-
Rounding means making a number simpler by keeping its value close to what it was.
For example: If we will round off 42 to the nearest ten, then the answer will be 40, because 42 is nearer to 40 than 50.
Now, let us take another example, say 46. So, when we will round off 46 to the nearest 10, then we will get 50 as the answer because 46 is closer to 50 than 40.
So, this is how we can round off numbers to the nearest 10.
Now, let us learn how to round off any number to the nearest 100.
Example: If we will round off 231 to the nearest hundred. We will get 200 because 231 is nearer to 200 than 300.
But, if we will take another example, say 268, then if we will round off it to the nearest 100, then we will get 300 as the answer because 268 is closer to 300 than 200.
So, this is how we can round numbers to the nearest 100.
