The length of piece of glass block was measured by means of a vernier calliper as shown above. The length of the glass block is

Answer Details

From the image provided, we can see that the zero error on the vernier calliper is 0.03 cm. The main scale reading that aligns with the zero mark on the vernier scale is 1.6 cm, and the vernier scale has an additional 0.04 cm of length that aligns with a main scale marking. Adding the main scale reading to the vernier scale reading (1.6 cm + 0.04 cm), we get a total length of 1.64 cm. Therefore, the length of the glass block is 1.64 cm.
