Question

Which unit would be most appropriate for measuring the volume of water in a swimming pool? Liters or Kiloliters

Answer 1

The volume of water in a swimming pool is best measured in kiloliters due to the large amount of water pools hold, making it a more suitable and manageable unit than liters.

Step-by-step explanation:

The most appropriate unit for measuring the volume of water in a swimming pool is kiloliters. When considering the size of a swimming pool and the large amount of water it holds, liters would be too small to effectively express this volume. Instead, using kiloliters, which represent thousands of liters, provides a more manageable and accurate measurement for such a substantial quantity of liquid.

It's important to select a unit that best corresponds with what is being measured. Since a swimming pool requires a significantly more substantial capacity for water compared to everyday containers, kiloliters are far more suitable than liters, which might be used for measuring smaller volumes, such as in a car's fuel tank. Hence, for the volume of a swimming pool, kiloliters are the ideal metric unit of capacity.

Answer 2

The most appropriate for measuring the volume of water in a swimming pool is kilolitres.

Consider a pool that is 25 m long by 10 m wide with an average depth of 1.5 m.

V = lwh = 25 m × 10 m × 1.5 m = 375 m³

1 L = 1 dm³, so

V = 375 m³ × (10 dm/1 m)³ = 375 000 dm³ = 375 000 L = 375 kL

Thus, the cubic metre or kilolitre is more appropriate, because it gives more manageable numbers (i.e., between 0.1 and 1000)
