Question

A swimming pool of 25m long and 20m wide is filled with water to a depth of 5m. what is the volume of water when it is 3/4 full?

Answer 1

`1875m^(3)`

Explanation:

To find
`(3)/(4)` of the volume, we first must know the total volume.

The formula to find volume:

`volume = length * width * depth`

We know the length is 25m, we know the width is 20m and we know the depth is 5m.

So, we can substitute them into the equation:

`volume=25*20*5=2500m^(3)`

Now we know the total volume, we can find out the volume when it is
`(3)/(4)` full:

`(3)/(4) * 2500 = 1875m^3`

Therefore, our final answer is
`1875m^(3)`.
