The length of the side of a cube is $1.2 \times 10^{-2} \ m$. Its volume up to correct significant figures is

For the four sets of three measured physical quantities as given below,which of the following options is correct?
$(i)$ $A_{1}=24.36, B_{1}=0.0724, C_{1}=256.2$
$(ii)$ $A_{2}=24.44, B_{2}=16.082, C_{2}=240.2$
$(iii)$ $A_{3}=25.2, B_{3}=19.2812, C_{3}=236.183$
$(iv)$ $A_{4}=25, B_{4}=236.191, C_{4}=19.5$

The decimal equivalent of $\frac{1}{20}$ up to three significant figures is

$A$ piece of length $3.532 \ m$ is cut from a rod of length $43.4 \ m$. The length of the remaining rod in metre is (up to correct significant figures)

The number of significant figures in the measured value $4.700 \,m$ is the same as that in the value ....... $m$

$Assertion$ : The number of significant figures depends on the least count of the measuring instrument.
$Reason$ : Significant figures define the accuracy of the measuring instrument.
