Six significant figures.

#### Explanation:

The first things to look for here are **non-zero digits**, which as you know are **always** significant.

This measurement has a total of **non-zero digits**

#2,3,8,2,3#

so right from the start you know that it will have *at least* five significant figures.

Now focus on the *trailing zero*. Trailing zeros are zeros that follow a non-zero digit and are **not** followed by other non-zero digits.

When trailing zeros follow a non-zero digit * and* a decimal place, they are considered significant. This means that your measurement will contain

**significant figures**
