input: Write a function to calculate the total surface area of a cuboid given its three dimensions. The function should return the total surface area.
  
  def find_total_surfacearea(length, breadth, height):
      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(0, 0, 0) == 0
output: def find_total_surfacearea(length, breadth, height):
      return (2*(length*breadth + breadth*height + height*length))
