1. rate = 27 km/hr
= 2700000 cm / 60 minutes
= 45000 cm/min
so in 1 minute, the water flows 45000 cm

volume = area of base x height
= 5.4 cm^2 x 45000 cm
= 243000 cm^3

3. As rate= 27km/h
So when we change it into cm it becomes =2700000cm/60mins
= 45000cm/min
So in 1minute 45000cm water is pumped
As the area of base is 5.4cm^2
So volume=area of base × height
5.4×45000
=243000cm^3
Hence,the volume of water pumped in one minute is 243000cm^3.
