Step-by-step explanation:
=> area of field = length × breadth
= 80m × 50m
= 4000 m^2
=> area of pit = 10m × 7.5m
=75m^2
=> area of field for spreading earth
= 4000m^2 - 75 lm^2
= 3975m^2
=> volume of earth taken out= l×b×h
= 10×7.5×8
=600
(area of field for spreading earth)×h= volume of earth taken out
=> 3975× h = 600
=> h= 600/3975
=> h= 0.151m
