Making use of the cube root table, find the cube root of the following (currect to three decimal places):

37800

Answer :

=


We know that value of


From cube root table we get,


=


So by unitary method,


For difference (180 – 170 = 10 ) difference in cube root values = 5.646 – 5.540 = 0.106


For difference (175 – 170 = 5) difference in cube root values =


=


Hence,


=


Thus, the required cube root is 33.558.
