How many inches is a length measuring 6 feet 10 inches?
There are 12 inches in a foot.
A. 62 inches
B. 72 inches
C. 13 inches
D. 82 inches
The Correct Answer and Explanation is:
To convert a length measured in feet and inches to inches only, you need to understand how to handle the conversion from feet to inches. Given a measurement of 6 feet 10 inches, we can break it down into two parts: the feet and the inches.
First, we need to convert the feet into inches. Since there are 12 inches in a foot, we can calculate the total number of inches in the feet portion as follows:
[
\text{Inches from feet} = \text{feet} \times 12
]
Substituting in our value:
[
\text{Inches from feet} = 6 \times 12 = 72 \text{ inches}
]
Next, we take into account the additional inches already provided in the measurement:
[
\text{Total inches} = \text{Inches from feet} + \text{inches}
]
Now substituting in the values:
[
\text{Total inches} = 72 + 10 = 82 \text{ inches}
]
Thus, the total length of 6 feet 10 inches is equivalent to 82 inches.
Now, looking at the provided answer choices:
- A. 62 inches
- B. 72 inches
- C. 13 inches
- D. 82 inches
The correct answer is D. 82 inches.
To summarize, when converting measurements from feet and inches to inches, the first step is to multiply the number of feet by 12 (the number of inches in a foot) to convert to inches. Then, add any additional inches that are part of the measurement. This method ensures that all units are consistent and allows for an accurate total measurement. By following this process for our specific measurement of 6 feet 10 inches, we accurately determined that the equivalent length in inches is 82 inches.
