A wooden block’s sides are measured using calipers. The side lengths are found to be $20.0\,\text{mm}$, $40.0\,\text{mm}$ and $10.0\,\text{mm}$. The calipers have an absolute uncertainty of $\pm 0.1\,\text{mm}$. What is the percentage uncertainty in the calculated volume of the block?
- A0.3\%
- B1.8\%
- C3.8\%
- D30\%
