A rectangular field is 70m long and 60m broad. A well of dimensions `14 m\ xx\ 8m\ xx\ 6m` is dug outside the field and the earth dug-out from this well is spread evenly on the field. How much will the earth level rise?

Explanation

Given that
Dimensions of rectangular field = `70m xx 60m`
Dimensions of well = `14m xx 8m xx6m `
Volume of well = `14 xx 8 xx 6`
` 672 m^3`
Let rise in earth level is h Spreading dugging soil on rectangle fill create a cuboid of height h.
The amount of dugging soil = volume of cuboid = volume of well
`70 xx 60 xx h = 14 xx 8 xx 6`
`h= (672)/( 4200 ) `
`0.16 m `
Rise in earth level
`h =16 cm`
