input: Write a function to calculate the total surface area of a cuboid given its three dimensions length, breadth, and height. Return the total surface area.
  
  assert find_total_surfacearea(2, 3, 4) == 52
  assert find_total_surfacearea(1, 1, 1) == 6
  assert find_total_surfacearea(5, 3, 2) == 62
  assert find_total_surfacearea(10, 5, 7) == 
output: def find_total_surfacearea(length, breadth, height):
      return 2 * (length * breadth + breadth * height + height * length)
