Volume- V-l3-1-2-xD7-10-x2212-2m-3-1-728-xD7-10-x2212-6m3Since length -l- has two significant figure- the volume -V- will also have two significant figure-Therefore- the correct answer is-xA0-V-1-7-xD7-10-x2212-6m3

A cube has a side of length $1.2 \times 10^{- 2} m$ . Calculate its volume.
$1.7 \times 10^{- 6} m^{3}$
$1.73 \times 10^{- 6} m^{3}$
$1.70 \times 10^{- 6} m^{3}$
$1.732 \times 10^{- 6} m^{3}$

Volume, $V = l^{3} = {(1.2 \times 10^{- 2} m)}^{3}$
$= 1.728 \times 10^{- 6} m^{3}$
Since length (l) has two significant figure, the volume (V) will also have two significant figure.
Therefore, the correct answer is $V = 1.7 \times 10^{- 6} m^{3}$

A cube has a side of length 1.2×10−2m. Calculate its volume.1.7×10−6m31.73×10−6m31.70×10−6m31.732×10−6m3

Volume, V=l3=(1.2×10−2m)3=1.728×10−6m3Since length (l) has two significant figure, the volume (V) will also have two significant figure.Therefore, the correct answer is V=1.7×10−6m3
