Question

A tank, 30 m long, 20 m broad and 12 m deep,
is dug in a field which is 500 m long and 30 m
wide. By how much will the level (in m) of the
field rise if the earth dug out is evenly spread
on the remaining part of the field ?​

Answer 1

Step-by-step explanation:

area of tank = lbh

30*20*12

7200

area of field = l*b

50*30

1500

level of field rise = 7200/1500

4.8 sq. m
