Estimate the value of the following square root to the nearest whole number square root 440

Answer 1

The value of the square root of 440 to the nearest whole number is  21.

Step-by-step explanation:

It is given that we have to estimate the value of √440 to the nearest whole number.

√440

∵ 20² = 400, 21² = 441 and 22² = 484

So 440 lies between 400 and 441

i.e., 400 < 440 < 441

⇒ 20² < 440 < 21²

⇒ 20 < √440 < 21

So, √440 basically lies between 20 and 21.

By using calculator we get, √440 = 20.9761

Thus, the estimated value of √440 to its nearest whole number will be 21.
