input: Write a function to find the total surface area of a cuboid, given its three dimensions (length, breadth, and height). Return the calculated 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(5, 6, 7) == 214
output: def find_total_surfacearea(length, breadth, height):
     return (2*(length*breadth + breadth*height + height*length))
