Question

muing the walls at Rs 3.50 per square metre.
11. A field is 150 m long and 100 m wide. A plot (outside the field) 50 m long and 30 m wide
is dug to a depth of 8 m and the earth taken out from the plot is spread evenly in the
field. By how much is the level of field raised?​

Answer 1

Answer:

0.8 m

Step-by-step explanation:

Length=150m

Breadth=100m

Area of field =lb=150*100

=15000m^2

Length of the hole=50m

Breadth=30 m

Depth= 8m

Volume=lbh=50*30*8

=12000m^3

Level of field which is raised= volume of soil dug/area of field =12000/15000

=12/15

=4/5=0.8m
