The volume of the cube is 216 cubic units what is the side length

Naddik [55]

The side length is six units.

A cube has three measurements: length, width, and height

All the measurements have to be the same.

This allows you to cube root.

The cube root of 216 is 6.

The side length of the cube is 6 units.

Check:

6 * 6 * 6 = 216.

It is correct, so our answer is proven to be correct.

In the diagram, GB = 2x + 3..

zaharov [31]

<u>Answer-</u>

$\boxed{\boxed{GB=15\ units}}$

<u>Solution-</u>

From the attachment,

AD = AE, so FA is a median.

BD = BF, so BE is a median.

CF = CE, so DC is a median.

And G is the centroid.

From the properties of centroid, we know that

The centroid divides each median in a ratio of 2:1

So,

$\Rightarrow FG:AG=2:1$

$\Rightarrow \dfrac{FG}{AG}=\dfrac{2}{1}$

$\Rightarrow FG=2\times AG$

$\Rightarrow 5x=2\times (x+9)$

$\Rightarrow 5x=2x+18$

$\Rightarrow 3x=18$

$\Rightarrow x=6$

So, GB will be $2(6)+3=15$ units
