Question

A field is 102 m long and 25 m broad. A tank 10 m long, 5 m broad and 4 m deep is dug out

from the middle of the field and the earth removed is evenly spread over the remaining part

of the field. Find the rise in the level of the remaining part of the field in centimetres​

Answer 1

Answer:

Let us take rise in level of the field =h cm

Vol. of the earth spread = vol. of the tank

Area of the remaining field times rise in level = vol. of the tank

(Area of field-area of tank)*rise in level of field= vol. of the tank

(120∗50−24∗10)∗h=24∗10∗6 thanks

(6000−240)∗h=1440

(5760)∗h=1440

=0.25m=25cm

rise in level of the field= 25cm
