Lea Boyer · Answer 1

Total room size: 60.6

# of significant digits: 3

Explanation:

One of the rules in significant figures is that trailing zeros to the right of the decimal are significant. Another is that numbers that aren't leading or trailing zeros always count. So say we have the number 600, the two zeros trailing after the six aren't significant figures, only the 6. Also, the number 006, the two zeros leading to six aren't significant too.
