A garden of area 2.5 sq m receives 25 mm of rainfall in one day. If 60% of the rainwater can be collected in a bucket, how many litres of water are collected in one day?

Step-by-step solution

1. Convert the rainfall depth from millimetres to metres: $25\text{ mm}=0.025\text{ m}$.
2. Multiply the depth by the area to get the volume of water that falls on the garden: $2.5\times 0.025=0.0625{\text{ m}}^3$.
3. Convert cubic metres to litres: $0.0625\times 1000=62.5\text{ litres}$.
4. Only 60% of this water is collected: $62.5\times 0.60=37.5\text{ litres}$.
