Question

solve the 8th question​

Answer 1

Answer:

first we have to find volume of cuboidal tank

so, volume of cuboid = l×b×h

= 7×6×15

= 42×15

= 630m³

now 1 m³ = 1000 liters

so, 630m³ = 630000 liters

8400 liters of water pumped out

therefore , 630000 - 8400

= 621600 liters

6,21,600 is the fall in the water level in the water tank

I hope this will help you
