Question

A cube has sides of length $1.2\times {10}^{-2}m.$ Calculate the volume.

• A. $1.728\times {10}^{-6}{m}^3$
• B. $1.73\times {10}^{-6}{m}^3$
• C. $1.70\times {10}^{-6}{m}^3$
• D. $1.732\times {10}^{-6}{m}^3$

Answer 1

The correct option is A $1.728\times {10}^{-6}{m}^3$

Given : $s=1.2\times {10}^{-2}m$

Volume $=s^3$$=(1.2\times {10}^{-2}{)}^{3}m=1.728\times {10}^{-6}{m}^3$
