# Digging

A pit is dug in the shape of a cuboid with dimensions 10mX8mX3m. The earth taken out is spread evenly on a rectangular plot of land with dimensions 40m X 30m. What is the increase in the level of the plot ?

Result

x =  20 cm

#### Solution:

$V=10 \cdot \ 8 \cdot \ 3=240 \ \\ S=40 \cdot \ 30=1200 \ \\ x=V/S \cdot \ 100=240/1200 \cdot \ 100=20 \ \text{cm}$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
