Hi guys,
I came across this question and don't understand why the answer is what it is, so I'd really appreciate it if someone could explain it to me

The real volume = 612,896.33cm3
Highest possible (error) = 614,617.58cm3
Lowest possible (error) = 611,178.09cm3

Question: "What is the absolute error for the volume of the cylindrical container?"

from this answer I'm assuming the formula would be that you reduce the 2 absolute errors by eachother :O???

not really sure what absolute error is but you guessed it that answer is the difference between the maximum and the minimum values of the volume

Absolute error: the furthest by which you can be wrong; equal to half the precision of the measuring device or half the smallest unit of measurement. But then again my teacher said our school did it differently...

Absolute error is the difference between an estimated or measured value and its actual value.

For example: 614,617.58 is the True value and 611,178.09 is the Recorded Value.

Hence: (True value) - (Recorded Value) = Absolute error (614,617.58) - (611,178.09) = 3439.49
