Question

The volume of the barrel is 4.6 m. It is half water. How many liters of water are there?​

Answer 1

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.
