first consider last digit is 3 so find out such number which cube gives last digit 3
such number is 7. because (7)³ = 343 here last digit is 3
now ignore the last 3 digit of the number 185193.
consider only 185.
now find the such cubic number that is very close to 185 but not more than 185.
such number is 125 that is (5)³
so first take 5 and then take 7
so cube root is 57.
