Question

A field is 40 m long and 30 m broad. In the centre of the field, a pit which is 10 m long and 2.5 m broad and 7 m deep has been dug out. The earth taken out of it is evenly spread over the remaining part of the field. Find the rise in the level of the field.



​

Answer 1

Step-by-step explanation:

area of field= 40*30= 1200 m2

area of pit=10*2.5=25 m2

volume of pit=10*2.5*7=175 m3

volume of earth taken out= 175 m3

earth spread on remaining area=1200-25=1175 m2

height*remaining area of land=volume of earth taken out

h*1175=175

h=175/1175

h=0.1489m
