Answer:
250,000 L
Step-by-step explanation:
we are given the fill rate of 500 m³ per hour , i.e.
in 1 hour ------> 500 m³ would have been added
if the fill rate is constant, then it reasons that in 1/2 hour, we would expect to see only 1/2 volume of water compared to a full hour , hence:
in 1/2 hour ------> 1/2 x 500 m³ = 250m³ would have been added
The question wants the answer in liters, however we have just calculated the volume in m³ above. Hence we need to convert 250m³ into liters
We note that 1 m³
= 1 m x 1 m x 1 m ( we are given that 1 meter is equal to 10 decimeters. substitute this into the equation,)
= 10 dm x 10 dm x 10 dm
= 1000 dm³
therefore 250m³ = 250 m³ x 1000 dm³ per m³= 250,000 dm³
we are further given that:
1 dm³ = 1 L, hence
250,000 dm³ = 250,000L
