Marks: +1, -0

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 litre) of water contained by each bucket is

Solution:

\;{2}/{3}

rd of the tank is emptied using 64 buckets.

∴

Volume of tank

=64 × \;{3}/{2}=96

buckets of water
Now, volume of each bucket

=\;{1.2 × 1.2 × 1.2 × 1000}/{96}

[ ∵ 1 {m}^{3}=1000

litre

]

=18
