Explanation:

Step1: Find main scale reading

The main scale reading (MSR) is the value on the main scale just before the vernier scale's zero mark. Here, MSR = $1.0$ cm

Step2: Find vernier scale coincidence

The 6th division of the vernier scale aligns with a main scale division. Vernier coincidence (VC) = $6$

Step3: Calculate vernier scale contribution

Vernier scale reading = $\text{VC} \times \text{L.C} = 6 \times 0.01 = 0.06$ cm

Step4: Sum readings for total measurement

Total reading = $\text{MSR} + \text{Vernier scale reading}$
<Expression>
$1.0 + 0.06 = 1.06$ cm
</Expression>

Answer:

$1.06$ cm
