Question

a field is 80 m long and 50 m broad in one corner of the field a pit which is 10 M long 7.5 m broad and 8 M deep has been dug out the earth taken out of it is evenly spread over the remaining part of the field find the rise in the level of the field

Answer 1

this question involves volume, and i doubt if volume is covered in 6th standard.

however lets try to find out the quantity of earth taken out= 10 x 7.5 x 8 = 600 cu.m

now this has to be uniformly spread on the area= (80 x 50) - (10 x 7.5)= 3925 sq.m

hence the remaning field will rise by = 600/3925 m = 0.1528m= 15.28 cm

Answer 2

Hope it helps you
