If the side length of a square pyramid is triple and the slant height is divided by 5 what would be the formula to find the modified surface area

If the original side length is "s" and the original slant height is "h", the original surface area is
.. S = (base area) +(lateral area)
.. S = s² +(1/2)*(4s)*h
.. S = s(s +2h)

Now, if we make these replacements: s ⇒ 3s, h ⇒ h/5, we have
.. S' = (3s)(3s +2h/5)
.. S' = 9s² +(6/5)s*h . . . . . . . the formula for the modified area (in terms of original dimensions)


Of course, in terms of the modified dimensions, the formula is the same:
.. S' = s'(s' +2h')
