Calculating the Difference in Height

Oct 13, 2025 by miodeya.com 16 views

Understanding the Problem

In this problem, we are given the heights of two individuals, Neha and Neeta, and we need to determine who is taller and by how many centimeters. To solve this problem, we need to convert the heights of both individuals to the same unit, which is centimeters.

Converting Neha's Height to Centimeters

Neha's height is given as 4 feet. To convert this to centimeters, we need to know that 1 foot is equal to 30.48 centimeters. Therefore, we can convert Neha's height as follows:

4 feet = 4 x 30.48 centimeters = 121.92 centimeters

Converting Neeta's Height to Centimeters

Neeta's height is already given in centimeters, which is 120 centimeters.

Comparing Heights

Now that we have both heights in centimeters, we can compare them to determine who is taller. We can see that Neha's height (121.92 centimeters) is greater than Neeta's height (120 centimeters).

Calculating the Difference in Height

To find out by how many centimeters Neha is taller than Neeta, we can subtract Neeta's height from Neha's height:

121.92 centimeters - 120 centimeters = 1.92 centimeters

Therefore, Neha is 1.92 centimeters taller than Neeta.

Conclusion

In conclusion, Neha is taller than Neeta by 1.92 centimeters.

Key Takeaways

To compare heights, we need to convert them to the same unit.
We can use conversion factors to convert between different units.
Subtracting one height from the other gives us the difference in height.

Real-World Applications

This problem has real-world applications in various fields such as:

Medicine: When measuring the height of patients, it's essential to use the same unit of measurement to ensure accurate comparisons.
Sports: In sports, athletes' heights are often compared to determine their competitive advantage.
Architecture: When designing buildings, architects need to consider the height of the structure and ensure that it meets local building codes and regulations.

Common Mistakes to Avoid

When solving this problem, some common mistakes to avoid include:

Not converting heights to the same unit: Failing to convert heights to the same unit can lead to incorrect comparisons.
Not using conversion factors: Not using conversion factors can result in inaccurate conversions.
Not subtracting one height from the other: Failing to subtract one height from the other can lead to incorrect calculations.

Practice Problems

To practice solving this type of problem, try the following exercises:

Compare the heights of two individuals, one of whom is 5 feet 6 inches tall and the other of whom is 160 centimeters tall.
Determine who is taller and by how many centimeters.
Convert the heights of both individuals to the same unit and compare them.

Conclusion

In conclusion, comparing heights requires converting them to the same unit and using conversion factors. By following these steps, we can accurately determine who is taller and by how many centimeters.
