A cube has a side of length 1.2 × 10−2 m.Its volume up to correct significant figures is

HereLength of the cube,  L = 1.2× 10−2mVolume of the cube, V = (1.2× 10−2m)3                                              = 1.728  × 10−6m3As the result can have only two significant figures  therefore, on rounding off, we getV = 1.7× 10−6m3
