Answer: 7 feet = 84 inches
Explanation
Understanding unit conversions is an essential part of everyday math, especially when working with measurements of length, height, or distance. In the United States and a few other countries, the imperial system is used for such measurements, where the foot is a common unit of length. One foot is equal to 12 inches. This is a standard and consistent conversion that does not change, regardless of the quantity being measured.
When you’re asked to convert a certain number of feet into inches, you simply multiply the number of feet by 12, because there are always 12 inches in every foot. In this case, we are converting 7 feet into inches. So we use the formula: Inches=Feet×12\text{Inches} = \text{Feet} \times 12
That gives us: 7×12=84 inches7 \times 12 = 84 \text{ inches}
This tells us that something that is 7 feet long is also 84 inches long.
Why is this useful? Imagine you’re measuring the height of a door, a basketball player, or even determining if a piece of furniture will fit in a room. In many situations, certain measurements might be given in feet, while others might be in inches. To compare them or use them together, you must convert them to the same unit.
Also, in fields like construction, interior design, tailoring, and sports, knowing how to quickly and correctly convert between feet and inches is important for accuracy. Mistakes in conversions can lead to big errors in planning or cost.
In conclusion, converting 7 feet to inches is simple: multiply by 12. The result is 84 inches. Understanding and being able to do these conversions helps with practical problem-solving and everyday tasks involving measurement.
