Question

Find the cube root of 1225 by estimation method.​

Answer 1

Answer:

10.69

Step-by-step explanation:

Answer 2

10.7

Now, for estimating, first we need to get the range i.e. we know that 10^3 = 1000

So the cube root of 1225 must be greater than 1000.

Now, cube of 11 = 1331. So range of cube root of 1225 = 10 < x < 11

Now if we look carefully at last 3 digits,

Cube of 6 = 216

Cube of 7 = 343,

so the number must be between 10.6 and 10.7

So the approximate answer will be 10.7 because it will be greater than 10.6.
