Find the length of the pencil shown on the scale.
The appropriate unit to measure an object like a pencil is centimetre.
If we observe the picture, the pencil on the scale starts at 1 cm and ends at 6 cm. Ideally, it should start from zero. So, we have to subtract 1 cm from 6 cm.
Length of the pencil = 6 cm − 1 cm = 5 cm
