Answer:
2300 liters of water.
Explanation:
The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.
Then the total volume of water inside the barrel is:
(4.6 m^3)/2 = 2.3 m^3
So we have 2.3 m^3 of water, and we want to write this in liters.
We know that 1 liter = 0.001 m^3
then:
1 = (1 L)/(0.001 m^3)
Now we can rewrite:
2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L
2.3 m^3 = 2300 L
So we have 2300 liters of water in the barrel.
