input: Write a function to find the total surface area of a cuboid given its three dimensions. The function should return the total surface area as an integer.
  
  def find_total_surface_area(length, breadth, height):
      return 2 * (length * breadth + breadth * height + height * length)
  
  assert find_total_surface_area(2, 3, 4) == 52
  assert find_total_surface_area(1, 1, 1) == 6
  assert find_total_surface_area(5, 10, 15) == 550
  assert find_total_surface_area(0, 0, 0) == 0
  assert find_total_surface_area(3, 4, 5) == 94
output: def find_total_surface_area(length, breadth, height):
      return 2 * (length * breadth + breadth * height + height * length)
