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.
