300m^3=300000000cm^3

300000000÷400

=750000cm^3

Answer 2

Answer:12 hours and 30 minutes

Step-by-step explanation:

As we know that,  1m^3=1000litres

Volume of water tank=10m*7.5m*4m=300m^3

                                   =300*1000=300000litre   (from the information given above)

For 400 litres it takes=1 minute

for 300000 litres it will take=1*300000/400

                                              =750 minutes

                                               =12hours and 30 minutes
