Question

Round this number to two significant figures.

634 L

630 L
640 L
44 L
34 L

Answer 1

To round the number 634 L to two significant figures, we look at the first two digits, which are 6 and 3. The next digit is 4, which is less than 5, so we do not round up.

Thus, 634 L rounded to two significant figures is **630 L**.
