Question 14

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 measures then the volume (in litres) of water contained by each bucketis

Solution

It is given that ,

$$\frac{2}{3}$$ of tank is emptied using 64 buckets ,

$$\frac{2}{3} V = 64 buckets$$

V = 96 buckets

Volume of each bucket

= $$\frac{1.2 \times 1.2 \times 1.2 \times 1000}{96} = 18 litres $$

So , the answer would be option b)18
