input: Write a function to take a list of numbers from 1 to 8 and print its cubic values.
  assert calculate_cubes([1, 2, 3, 4, 5, 6, 7, 8])==[1, 8, 27, 64, 125, 216, 343, 512]
  assert calculate_cubes([1, 2, 3])==[1, 8, 27]
  assert calculate_cubes([])==[]
  assert calculate_cubes([5, 6])==[125, 216]
  assert calculate_cubes([8])==[512]
output: def calculate_cubes(numbers):
      return [x**3 for x in numbers]
