input: Write a function to calculate the total surface area of a cuboid given its length, breadth, and height. Return the calculated surface area. The function should 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(5, 2, 3) == 62
  assert find_total_surfacearea(0, 0, 0) == 0
  assert find_total_surfacearea(3, 4, 6) == 84
output: def find_total_surfacearea(length, breadth, height):
      return 2 * (length * breadth + breadth * height + height * length)
