    The length, width and thicknesss of a block are \[(100.0\pm 0.1)cm,\] \[(10.00\pm 0.01)cm\] and \[(1.000\pm 0.01)cm\] respectively. The maximum possible error in its volume will be:

    A)  \[\pm \,0.111\,c{{m}^{3}}\]           

    B)  \[\pm \,0.012\,c{{m}^{3}}\]

    C)  \[+\,0.003\,c{{m}^{3}}\]               

    D)  None of these

    Correct Answer: C

    Solution :

    Error in the volume is given by \[\frac{\Delta V}{V}=\frac{\Delta l}{l}+\frac{\Delta b}{b}+\frac{\Delta t}{t}\]   (as   \[V=lbt\]) From the data, the question maximum error would be \[0.003\,c{{w}^{3}}\]
