Question

A tank has a capacity of $3584m^3$ that is used by 4 families. If each family uses 4 buckets of water every day, and the volume of the bucket is $16m^3$, then the water in the tank will last for how many weeks?

• A. 2 weeks
• B. 3 weeks
• C. 1 week
• D. 4 weeks

Answer 1

The correct option is A

2 weeks

A family uses 4 buckets of water each measuring $16m^3$.
$\therefore$ The total amount of water each family uses $=64m^3$.
So, 4 families will consume $256m^3$of water every day.

Therefore number of days required to empty $3584m^3$ of water $=\frac{3584}{256}=14$

Therefore, water in the tank will last for 2 weeks.
