input: Write a function to generate a list of 'n' cubed objects with random coordinates.
  assert len(generate_cubed_object(5)) == 5
  assert all(len(obj) == 3 for obj in generate_cubed_object(10))
  assert all(0 <= coord <= 1 for obj in generate_cubed_object(7) for coord in obj)
output: import random
  
  def generate_cubed_object(n):
      return [[random.uniform(0, 1) for _ in range(3)] for _ in range(n)]
