Answer:

4mm

Step-by-step explanation:

The side length of a cube can be found using the formula given in the question.

V = S^3, with V being volume and S being the side length.

After substituting V for 64, we can solve for S to find the side length.

64 = S^3

S = 4

That forms a right triangle, so use the Pythagorean theorem. 5^2+2^2=c^2
25+4=c^2
c=√29

Complete question

To find $\sqrt{5}$ , Beau found $2^2 = 4$ and $3^2 = 9$ . He said that since 5 is between 4 and 9, $\sqrt{5}$ , is between 2 and 3. Beau thinks a good estimate for $\sqrt{5}$ , is $\frac{2 + 3}{2} = 2.5$ Is his estimate high or low? How do you know?

Answer:

The estimation is high because 5 is very close to 4 so $\sqrt{5}$ will also be very close to $\sqrt{4}$ which is lower than the estimate

In order to get a good estimate

The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them

i.e

$2.1^2 = 4.41$

$2.2^2 = 4.84$

$2.3^2 = 5.29$

From here we can see that $\sqrt{5}$ lies between 2.2 and 2.3 but is closer to 2.2

So a good estimate for $\sqrt{5}$ is 2.2
