# Find the Volume (in litres) of Water Contained by Each Bucket :

If 64 buckets of water are removed from a cubical shaped water tank completely filled with water, 1/3 of the tank remains filled with water. The length of each side of the tank is 1.2 m, Assuming that all buckets are of the same measure, then the volume (in litres) of water contained by each bucket is

- 12
- 16
- 15
- 18

**Answer is (4): 18**

**Explanation:-**The side of a tank = 1.2 m

Then, the volume of a tank = (1.2)

^{3}

= 1.2 x 1.2 x 1.2

= 1.728 m

^{3}

Water tank filled with water = 1-1/3 => (3 – 1)/3

= 2/3

The volume of 64 buckets water = 2 x 1.728/3

= 1.152 m^{3}

1m^{3} = 1000 litres

Therefore, 0.576 m^{3} = 1.152 x 1000

= 1152 litres

Then, the water contained by buckets = 1152 litres

Therefore, water contained by each bucket = 1152/64

= 18 litres

Then, the volume of (in litres) of water contained by each bucket is 18 litres.

Hence, the answer is (4) 18 litres.
