Question

the depth of a cuboidal pond with length of 20m.and breadth of 18.5m is 3.2? let us write by calculating, time required to irrigate whole water of the pond with a pump having the capacity to irrigate 160 kilo lit.water per hour.if that quantity of water is poured on a paddy fields with a ridge having the length of 59.2m and breadth of 40m., then what is the depth of water in that land let us write by calculating it(1 cubic metre=1 kilo litre)​

Answer 1

Answer:

1 kilolitre= 1 cubic merte <br>

160 ,, = 160 ,, ,, <br> The length of the pond = 20 metres, breath = 18.5 metres and depth of water in the pond =3.2 metres. <br>

the volume of water

cu meters = 1184 cu - metres <br> The pump irrigate 160 cu-meters in 60 minuts <br>

,, ,, ,, ,, ,, ,, 1 ,, ,, ,, ,,

,, <br> ,, ,, ,, ,, ,, 1184 ,, ,, ,,

minutes =7 hours 24 minutess <br> Again, let the depth of water after pouring water in the paddy field be x metre. <br> Then, the volume of water in the field

cubic-metre. <br> As per question .

<br> or,

<br> Hence the required time to iITigate the water of the pond is 7 hours and 24 minutes and the depth of water in the paddy field after pouring the water of the pond in it will be 0.5 metre = 5 dcm
