yes , they are lengthy , but unfortunately there are no other way to do that , u need to follow the same formula , 
d = z.m / a cube * avg no . 
and while putting a value try to make round figure as much as possible , and u need to guess the correct answer in entrance exam in this type of ques after u calculated it approximately . 
ALL THE BEST
