# 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 :

Given,

Length of field = 150m

Width of field = 100m

Area of field = 150m × 100m = 15000 m2

Length of plot = 50 m

Breadth = 30 m

Depth upto which it dug = 8 m

So volume of earth taken out from it = 50×30×8 = 12000 m3

let raise in earth level of field on which it spread = h metre

so,

=

=

The level of field raised by 0.8 metre
