Answer 2

Step-by-step explanation:

$lenght = distance = speed \: \times time \\ 6 \times 1000 \times 1 \div 60 \\ 6000 \div 60 = 100km \: is \: the \: lenght \: \\ \\ now \: volume = lbh = 100 \times 50 \times 15 = 75000m {}^{3} \\ \\ and \: we \: know \: that \: 1 \: m {}^{3} = 1000litre \: so \: 75000000litres$
