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

7342

=


We know that value of


From cube root table we get,


=


So by unitary method,


For difference (7400 – 7300 = 100 ) difference in cube root values = 19.48 – 19.39 = 0.09


For difference (7342 – 7300 = 42) difference in cube root values =


=


Thus, the required cube root is = 19.427.
