Question

is the total surface are S of a cube a function of the edge length x of the cube?

Answer 1

Is the question: What is the Total Surface Area of a cube when the length is X?

Answer 2

no, its asking if it is even a function to begin with. then it says: if so, write the function rule s(x) and evaluate s(3). and if not, why?

Answer 3

\[s(x)=6x^2\]
Where S is the Surface area of the cube
Is that it?
If so, substitute 3 for x and see the TSA

Answer 4

I mean S is Surface Area, X is side value

Answer 5

that sounds about right! thanks!

Answer 6

sub value 3 into equation:
\[s(x)=6x^2\]
\[s(3)=6*3^2\]
\[s(3)=6*9\]
\[s(3)=54\]
