Question

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(4) = 64?

Answer 1

I would interpret that the side of the cube is four since the volume of the cube is cube of the side. In this case 4 is the side and 4x4x4=64.

Answer 2

Let

s-------> the length side of a cube

we know that

the volume of a cube is equal to

`V=s^(3)`

the volume of a cube written in function notation is equal to

`V(s)=s^(3)`

For
`s=4\ units`

the volume is equal to

`V(4)=4^(3)=64\ units^(3)`

therefore

the answer is

the best interpretation is

For a length side of a cube equal to
`4\ units` the volume is equal
`64\ units^(3)`
