input: Write a function to find the total surface area of a cuboid, given its three dimensions. The total surface area can be calculated using the formula: 2*(length*breadth + breadth*height + height*length). If any of the dimensions are non-positive, return 0.
  
  def find_total_surfacearea(length, breadth, height):
      if length <= 0 or breadth <= 0 or height <= 0:
          return 0
      return (2*(length*breadth + breadth*height + height*length))
  
  assert find_total_surfacearea(2, 3, 4) == 52
  assert find_total_surfacearea(1, 1, 1) == 6
  assert find_total_surfacearea(5, 5, 5) == 150
  assert find_total_surfacearea(0, 3, 4) == 0
  assert find_total_surfacearea(2, -1, 4) == 0
output: def find_total_surfacearea(length, breadth, height):
      if length <= 0 or breadth <= 0 or height <= 0:
          return 0
      return (2*(length*breadth + breadth*height + height*length))
