The length $l$, breadth $b$ and thickness $t$ of a block of wood were measured with the help of a measuring scale. The results with the permissible errors are $l=\left(15.12\pm 0.01\right) \mathrm{cm}$, $b=\left(10.15\pm 0.01\right) \mathrm{cm}$ and $t=\left(5.28\pm 0.01\right) \mathrm{cm}$. The percentage error in its volume up to $2$ proper figures is
