Step-by-step explanation:

Cube root of 274625

Step 1: Form groups of three starting from the rightmost digit of 274625

274625

One group i.e., 274 has two digits whereas 625 has only one digit.

Step 2: Consider 625. The digit 5 is at its one’s place.

We take the one’s place of the required cube root as 4

Step 3: Consider the other group, i.e.274

The number 274 ends with 4. it lies between the

6 cube= 216 and 7 cube=343. We will take the smallest which is 6.

Take 6 as the ten’s place of the cube root of 274625.

Thus, 274625= 65.
