Question

Andy is 6 feet tall. If 1 inch is 2.54centimeters then how tall is Andy to the nearest centimeters.

Answer 1

Hint: Now we are given that Andy is 6 feet tall. Now since 1 feet is 12 inches we will multiply by 12 to find the height in inches. Then we have that 1 inch is 2.54 centimeters, hence we will multiply by 2.54 centimeters to find height in centimeters. Hence we have the height of Andy in centimeters.

Complete step-by-step answer:
Now let us first understand the concept of measurement. Measurement is a concept which we use to assign a number to find the amount of something. Hence we can quantify things with the help of measurement.
Now length is also a measure which denotes how tall a thing is.
Now to measure things we have different units. Units are assigned standardly to measure the something precisely.
Now to measure length we have different units. Some of the common units to measure lengths are centimeters, meters, kilometers, inches and feet.
Each unit can be converted into another in a standard way.
For example 1 feet is 12 inches. 1 inch is 2.54 centimeters, 1 kilometers = 1000 meters, 1m = 100 centimeters.
Now consider the height of Andy.
Andy is 6 feet tall.
Now we know that 1 feet is 12 inches.
Hence we can say that 6 feet is 6 × 12 = 84 inches.
Hence Andy is 84 inches tall.
Now again we know that 1 inch is 2.54 centimeters.
Hence 84 inches is 2.54 × 84 = 213.36 centimeters.
Hence Andy is 213.36 centimeters tall.

Note: Note that when we have 1m = 100centimeters then if we want to convert from meters to centimeters we will multiply by 100 and if we want to convert from centimeters to meters we will divide by 100. Similarly we will convert to other units as well.
