Answer 1

The length of the match box=4.3-1

3.3cm

Hence its length is 3.3cm

Hope it helps.

Answer 2

The length of the matchbox is 3.3 cm.

- When we are measuring any kind of length by the help of a measuring scale.

The measurement = The reading of the lower end - The reading of the higher end.

- Now,in the normal cases,the lower end is taken the 0th reading of the scale.

That's why the higher end's reading is always the actual measurement.

(A number - 0 = The number itself)

- But here,the lower end's reading is not zero.

So,the actual measurement = (4.3 - 1.0) = 3.3 cm (answer)
