input: Write a function to calculate the total surface area of a cuboid given its three dimensions. If the given dimensions are negative or zero, return 0. The function should be named find_total_surfacearea and take three parameters: length, breadth, and height.
  assert find_total_surfacearea(2, 3, 4)==52
  assert find_total_surfacearea(1, 1, 1)==6
  assert find_total_surfacearea(0, 0, 0)==0
  assert find_total_surfacearea(-2, 3, 4)==0
  assert find_total_surfacearea(4, 5, 6)==148
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)
