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?

Answer 1

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.
