A square with an area equal to 256 has its center at the origin, (0,0), in the xy-coordinate plane. The graph of a function f is defined by \(f(x)=cx^3\), for some positive constant c, intersects the square at two opposite vertices of the square. What is the value of C? (Enter your answer as a fraction?)

Possible intersections points: (8,8) or (-8,-8)
So given x=8, y=8 and for function f(x=8) = c*8*8*8
c*8*8*8 = 8
=> c = 1/64
So given x=8, y=8 and for function f(x=8) = c*8*8*8
c*8*8*8 = 8
=> c = 1/64
