Answer 2

Answer:

Step-by-step explanation:

Length of the field=20m

Breadth of the field =14m

Volume of the well =volume of raise in field (i)

There fore,volume of cylindrical well=πrrh

=22÷7×7÷2×7÷2×10

=385cubic m

From(i),

Volume for raise in field = l×b× h=385

14×20×h=385

385÷14×20=h

This implies height of raise in field =1.35m
