The thicknes of a glass plate is measured to be 2.17 and 2.17 mm and 2.18 mm at three different places. Find the average thickness of the plate from this data.

Text Solution

Verified by Experts

The correct Answer is:
2.17 mm
We know that, averge thickness=`(2.17+2.17+2.18)/3`
=2.1733mm Rounded of to 3 significant digits,
Average thickness =2.17 mm.
