input: Write a function to calculate the total surface area of a cuboid given its three dimensions. The function takes three arguments: length, breadth, and height. It should 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, 10, 2)==160
  assert find_total_surfacearea(0, 0, 0)==0
  assert find_total_surfacearea(7, 3, 9)==270
output: def find_total_surfacearea(length, breadth, height):
      return 2 * (length * breadth + breadth * height + height * length)
