Remember
xyz=(x)(y)(z)
if x and y and z are all perfect cubes, xyz is also a perfect cube

remmeber
(x^n)^m=x^(mn)
so if it is perfect cube it can be factored into
(x^n)^3, such taht n is a whole number
basiclaly, see if the expoent is divisble by 3

all of them should be perfect cubes

215x^18y^3z^21

split them up to see which ones need changing

215=5*43, not  a perfect cube
could be changed to 6^3, which is 216

x^18=(x^6)^3

y^3=y^3
z^21=(z^7)^3

the 215 needs to be changed

Carlos is giving his friend in another state a new umbrella as a gift. He wants to ship the umbrella in a box he already has. Wh
notka56 [123]

Answer:

<h2>He could use the medium box.</h2>

Step-by-step explanation:

Notice that the umbrella is 37.5 inches long.

If you observe, each box doesn't have 37 inches wide, however, they are tridimensional figures, which means they have a certaing height.

So, the smalle box is too small to fit the umbrella.

But, the medium box is perfect, because it has 27 inches wide and 27 inches height, which is enough to fit the umbrella. These are the best dimensions to send the umbrella.

Therefore, the medium box is the answer, the one that has dimensions 27x14x27.
