| Given the volume of the ball = 36 * n cm ^ 3, we need to find the surface area of the ball. In order to solve this problem, we need the formulas of the ball:
Volume of the sphere: V = 4/3 * n * R ^ 3;
Surface area of the ball (sphere): S = 4 * n * R ^ 2.
Using the volume of the ball, we find the radius of the ball:
4/3 * n * R ^ 3 = 36 * n;
R ^ 3 = 36 * 3/4;
R ^ 3 = 27;
R = 3.
The radius of the ball is 3 and using this we find the surface area of the ball:
S = 4 * n * R ^ 2 = 4 * n * 3 ^ 2 = 36 * n.
Answer: The surface area of the ball is 36 * n cm ^ 2.
