हिन्दीThe length of three rods are measured as \( 15.24\text{ cm} \), \( 0.082\text{ cm} \), and \( 1.3\text{ cm} \). Their total length, expressed with due regard to significant figures, is:
Correct answer · Option 3
\( 16.6\text{ cm} \)
Explanation
In addition, the final result retains as many decimal places as the number with the least decimal places (\( 1.3\text{ cm} \) has 1 decimal place). Total \( = 15.24 + 0.082 + 1.3 = 16.622 \rightarrow 16.6\text{ cm} \).
