Question

While measuring the length of a paper clip on a scale, the reading at one end is 1.0 cm and at the other is 4.3 cm. What is the total length of the paper clip?​

Answer 1

Answer:

The actual length of the paper clip is 3.3 cm.

We generally measure the length of any object

by different measuring scales.

- We start the measurement by taking the

'O' marking on the scale as one end of the

object,then the another end of that object will

be situated right beside it's length marking on

the scale.

- If that's not the case and we don't take

measurement from the zero marking, then the

measurement is calculated by calculating the

difference between the starting end marking

and finishing end marking.

Actual length = (Finishing marking - Starting

marking)

- Similarly, here the actual length of the paperclip

is = (4.3-1.0) = 3.3 cm.
