The dimensions of a field are 10 m by 10 m. A pit 5 m long, 5 m wide and 3 m deep is dug in one corner of the field and the earth removed has been evenly spread over the remaining area of the field. What will be the rise in the height of field as a result of this operation ? Choose one:
A) 2m
B) 2.5m
C) 1.5m
D) 1.25m
E) 1m
The volume of the earth removed is 5*5*3=

75 m^3.   The remaining area of the field is   10*10 - 5*5= 
<gadget id="calculator">  10*10 - 5*5</gadget>
<output>75</output>
75 m^2.   75 m^3 of the earth evenly spread over the area of 75 m^2 will rise the height by (height)= (volume)/(area) = 75/75=
