a measurement of 83200 ft. converted to (8.32)x10^4 ft. is now accurate to the nearest hundred feet. if we write (8.320)x10^4 the measurement is now accurate to the nearest ten feet.

i want to know why it is nearest to a hundred feet in the first conversion and nearest to ten feet in the second.

thanks!
