input: Write a function to find the total surface area of a cuboid given its three dimensions.
  def find_total_surfacearea(length, breadth, height):
     return (2*(length*breadth + breadth*height + height*length))
  
  print(find_total_surfacearea(2, 3, 4))
  assert find_total_surfacearea(2, 3, 4)==52
  assert find_total_surfacearea(1, 2, 3)==22
  assert find_total_surfacearea(5, 5, 5)==150
output: def find_total_surfacearea(length, breadth, height):
     return (2*(length*breadth + breadth*height + height*length))
