Question
While measuring the length of a knitting needle, the reading of the scale at one end is 3.0 cm and at the other end is 33.1 cm. What is the length of the needle?
Solution
The reading of the scale at one end is 3 cm and at the other end is 33. 1 cm.
Therefore, the length of the knitting needle is given by subtracting both the readings, i.e.,
(33.1 - 3.0) cm = 30.1 cm.
