What is the similarity ratio of a cube with volume 729m^3 to a cube with volume 3375 m^3

liubo4ka [24]

<u>Answer:</u>

3/5

<u>Step-by-step explanation:</u>

We are to find the similarity ratio of a cube with volume $729 m^3$ to a cube with volume $3375 m^3$ .

We know the formula for the ratio of two cubes:

$\frac{V_1}{V_2} =k^3$

where $k$ is the similarity ratio of the two cubes.

Substituting the given values in the formula to find $k$ :

$k^3 = \frac {729} {3375}$

$k^3 = \frac {27} {125}$

$k^3 = (\frac {27} {125})^3$

$k=\frac{3}{5}$

Therefore, the similarity ratio of the two cubes is 3/5.

(20 POINTS AND BRAINLIEST) The rectangles below have the same perimeter

Bezzdna [24]

Answer:

Well it is 16

Step-by-step explanation:

the rectangle has 2 of the same sides for each side, so 3x2+5x2, a square has all sides equal to each other, so 4x4

So Now we do the easy part|
The rectangle that is grey:
3x2 = 6
5x2 = 10
6+10 =16

The orange square:
4x4 = 16
4+4=8
4+4=8
8+8=16

Therefore both are 16, meaning 16 must be the perimeter for both!
