Answer:
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 these measurements.
Add all the given measurements.
[tex]Total=28 L+42 L+6 L +931 L[/tex]
It can be written as
[tex]Total=(28+42+6+931)L[/tex]
On simplification we get
[tex]Total=1007 L[/tex]
Therefore the sum of given measurements is 1007 L.
