Question:
Find the cubes of the following numbers by column method:
(i) 35
(ii) 56
(iii) 72
Solution:
(i)
We have to find the cube of 35 using column method. We have: $a=3$ and $b=5$
Thus, cube of 35 is 42875.
(ii)
We have to find the cube of 56 using column method. We have: $a=5$ and $b=6$
Thus, cube of 56 is 175616.
(iii)
We have to find the cube of 72 using column method. We have: $a=7$ and $b=2$
Thus, cube of 72 is 373248.
