What is cube of any number ?

Cube of any number means multiplying that number with itself 3 times.

For example [tex]3^3=3\times3\times3=27[/tex]

Here given phrase is

twice the sum of a number cubed and nine

let number be r

We can write it as

[tex]2(r^3+9)[/tex]

Now evaluating it for r=3

[tex]2(3^3+9)[/tex]

Now we can simplify it as

[tex]2(27+9)\\\\=(36)\\\\=72[/tex]
