Answer :

To determine the height of the swimming pool, we need to use the relationship between the volume of the pool and its dimensions. Here's a step-by-step solution:

1. Understanding the given data:
- The capacity of the swimming pool is 3000 kiloliters (kl).
- The length of the swimming pool is 50 meters (m).
- The width of the swimming pool is 20 meters (m).

2. Unit Conversion:
- 1 kiloliter (kl) is equivalent to 1 cubic meter (m³). Therefore, 3000 kiloliters is equal to 3000 cubic meters (m³).

3. Volume Formula:
- The volume [tex]\(V\)[/tex] of a rectangular prism (which the swimming pool resembles) is given by the formula:
[tex]\[ V = \text{length} \times \text{width} \times \text{height} \][/tex]
In our case:
[tex]\[ V = 3000 \, \text{m}^3 \][/tex]
[tex]\[ \text{length} = 50 \, \text{m} \][/tex]
[tex]\[ \text{width} = 20 \, \text{m} \][/tex]
We need to find the height [tex]\(h\)[/tex].

4. Rearranging the formula to solve for height:
[tex]\[ h = \frac{V}{\text{length} \times \text{width}} \][/tex]

5. Substituting the given values:
[tex]\[ h = \frac{3000 \, \text{m}^3}{50 \, \text{m} \times 20 \, \text{m}} \][/tex]

6. Performing the calculation:
[tex]\[ h = \frac{3000 \, \text{m}^3}{1000 \, \text{m}^2} \][/tex]

Simplifying the right-hand side:
[tex]\[ h = 3 \, \text{m} \][/tex]

So, the height of the swimming pool is 3 meters.
