Substituting in you get 4(-1)^3 * (2)^2. -1 cubed is -1 and 2 squared is 4. So you get -4*4 = -16 as your answer.
A = 2 * a^2 * (1 + sqrt 2)
Where 'a' is the side length.
A = 2 * 10^2 * (1 + sqrt 2)
A = 2 * 10^2 * 2.41421356
A = 2 * 100 * 2.41421356
A = 200 * 2.41421356
A = 482.842712
Therefore, the closest one is C.
