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.
  
  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, 2, 7)==118
  assert find_total_surfacearea(0, 0, 0)==0
  assert find_total_surfacearea(3, 4, 5)==94
output: def find_total_surfacearea(length, breadth, height):
     return (2*(length*breadth + breadth*height + height*length))
