This isn’t accurate because they didn’t round the numbers correctly. for example, if a decimal is 7.5, you would usually round it up to 8, so anything higher should also be rounded to 8. the fact they rounded 7.95 to 7 doesn’t make sense as it’s much closer to 8 than it is to 7.
First you need to find how many inches is in 6.2 feet which is 74. Then you need to multiply that by 2.54 to get the amount of centimeters. Which is 182.88. So the answer is 182.88
