What is the relationship of the volume of the cube to its edge length

If x is the volume and y is the edge length, the general equation would be

y = k*(x^3)

The relationship between the edge length  and the volume  is a direct variation, but it is not linear.

Step-by-step explanation:

Let's call each edge length as .

By definition, we know that the volume of a cube is

Through this expression, you can deduct that the volume of the cube is directly proportional to its edge, that means the volume depends totally on the edge length. A direct proportion means that if the length of the edge increases, then the volume will also increase. This proportion is written like this

This expression represent all we said before, the volume is directly proportional to its edge length.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
