A tank having a capacity of 4096 m3 is used by 4 families. If each family uses 4 buckets of water every day and the volume of the bucket is 16 m3, then the water in the tank will last for at least how many weeks?
2
Number of buckets measuring 16 m3 used by each family = 4
∴ Total amount of water used by each family =64 m3
So, Amount of water used by 4 families = 256 m3
Therefore, number of days required to empty 4096 m3 of water =4096256=16
Therefore, water in the tank will last for at least 2 weeks.
