Question: 
Write a function to find the surface area of a cuboid.


Model's Code:
def surfacearea_cuboid(length, width, height):
    return 2 * (length * width + width * height + height * length)



Sample Correct Code:
def surfacearea_cuboid(l,w,h):
  SA = 2*(l*w + l * h + w * h)
  return SA


Asserts:
assert surfacearea_cuboid(1,2,3)==22
assert surfacearea_cuboid(5,7,9)==286
assert surfacearea_cuboid(10,15,21)==1350
