Answer
Given:
Area of cross section = 12 cm2
Speed of water = 20 cm/s
Volume of water flowing out per second = Area of cross section x speed of water
= 12 x 20 cm3
= 240 cm3/s
Volume of water flowing out per minute = 240 x 60 cm3
= 14,400 cm3
= 0.0144 m3
The total volume of water flowing out in one minute is 0.0144 m3.
Hence, option 1 is the correct option.
