A cube has a side of length `1*2xx10^(-2)`m.

Options

A. `1.7xx10^(-6)m^(3)`
B. `1.73xx10^(-6)m^(3)`
C. `1.70xx10^(-6)m^(3)`
D. `1.732xx10^(-6)m^(3)`

Answer

A

Explanation

Here volume`=(1*2xx10^(-2))^(3)=1*728xx10^(-6)m^(3)` Since the minimum number of significant figures in length `1*2xx10^(-2)` is only two, the same should hold good for the volume. Hence the answer is `1*7xx10^(-6)m^(3)`.
Hence correct choice is `(a)`.
