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

833

=


We know that value of


From cube root table we get,


=


So by unitary method,


For difference (840 – 830 = 10 ) difference in cube root values = 9.435 – 9.398 = 0.037


For difference (833 – 830 = 3) difference in cube root values =


= = 9.409


Thus the required cube root is = 9.409.
