Question

stimate the cube root of the following numbers upto one decimal place 255​

Answer 1

Answer:

First establish the nearest integer cubes. In this case

•6³ = 216

•7³ = 343

→ 216 < 255 < 343. So you know you will have an answer that is 6.x

→ To approximate what the tenth will be, simply take the difference of 6³ and 7³ =

343 - 216 = 127.

Now divide the difference between 255 into this.

➠255 - 216 = 39

➠39/127 = .307

••••••This will round to .3, and you have your x. The answer then is 6.3 which you can confirm by taking 6.3³ = 250.04 and compare it to 6.4³ = 262.1.

total answers:- 6.3 if we do estimation

hope this will help you~~~~
