उत्तर
Length of book = l = 25 cm
Breadth of book = b = 18 cm
Height of book = h = 2 cm
Volume of book = l × b × h
V = 25 × 18 × 2
V = 900 cm3
V = `900/10^6"m"^3`
V = `9/10000"m"^3`
V = 0.0009 m3

Figure shows the position of vernier scale while measuring the external length of a wooden cylinder.
- What is the length recorded by the main scale?
- Which reading of vernier scale coincides with the main scale?
- Calculate the length.
(a) A vernier scale has 20 divisions. It slides over the main scale, whose pitch is 0.5 mm. If the number of divisions on the left hand of the zero of vernier on the main scale is 38 and the 18th vernier scale division coincides with the main scale, calculate the diameter of the sphere, held in the jaws of vernier callipers.
(b) If the vernier has a negative error of 0.04 cm, calculate the corrected radius of the sphere.
What do you understand by the following term as applied to screw gauge?
Positive zero error
How the backlash error is avoided?
