What you need to check

Significant figures count the digits in a measured value that carry meaning. The main thing to watch for here is whether the zero counts.

Counting the digits in 2.067

Write out the digits: $2.067$ has the digits $2$, $0$, $6$, and $7$.

• $2$, $6$, and $7$ are nonzero, so they are significant.
• The $0$ is between nonzero digits ($2$ and $6$), so it is also significant.

So there are $4$ significant figures.
