Volume of water coming out in 1 HR= 6×1.5×10,000 meter cube.
Volume of water in 30 min= 45,000 meter cube.
height of water = 8cm = 0.08m
Area covered
0.08×A= 45,000
A= 562500 meter square

how do u find the volume i first sentence what is the formula
and how u find the area in 8th line
cuboid
lenght×bredth×height
height is 1.5 breadth is 6 and for one hour length is 10,000m
Base area × height gives the volume so the water dropped from river equals to the volume of water used in irrigation
0.08 is height and base area A is unknown.
thanks u r great bcz u have helped in such a crictical time
