Answer:
The most appropriate unit for measurement of water conserved or stored is the acre-foot , if the conserved volume is low then the ideal unit is cubic foot.
Step-by-step explanation:
- One acre corresponds to 43560 square feet area
- Likewise 1 acre-foot will be equal to 43560 cubic feet
- In terms of gallon 1 acre-foot corresponds with 3,25,851 gallons of water.
- In terms of cubic meter, 1 acre-foot is equal to 1233 cubic meters of water
- As the above conserved water is pertaining to household reserve so 1 cubic -foot would be ideal unit for measurement.
- 1 cubic foot corresponds to 7.4805 unit of water in gallons.
