Your answer should indicate the proper precision (correct number of insignificant figures).

1. 1,010 L
2. 1,007.0 L
3. 1,007 L
4. 1,000 L

The sum of given measurements is 1007 L.

Explanation:

The given measurements are 28 L, 42 L, 6 L, and 931 L.

We need to find the total of these measurements.

Total = 28 L + 42 L + 6 L + 931 L

It can be written as

Total = ( 28 +42+6+931)

One simplification we get Total = 1007 L
