volume = depth \times length \times width

Depth = 15 m

width = 50 m

length = ?

so,

length = speed of water * time

length =  \frac{2}{100}  \times 9 \times 3600 \: m

length = 648 \: m

now,

volume = 15 \times 50 \times 648  \: {m}^{3}

as we know,

1 \:  {m}^{3}  = 1000l

so,

volume \:  = 15 \times 50 \times 648 \times 1000

volume = 486000 \: l
