Let's take a look at this problem.
Rectangle Perimeter = 2(l + w)
Rectangle Perimeter =? 2(2l + 2w)
Rectangle Perimeter =? (2)(2)(l + w)
2(Rectangle Perimeter) = 2[2(l + w)]
Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.
Rectangle Area = lw
Rectangle Area =? (2l)(2w)
Rectangle Area =? 4lw
4(Rectangle Area) = 4lw
Thus, we can say that the area of a rectangle is quadruplicated when its dimensions are doubled.

The effect on the total surface area of one dimension being doubled or tripled cannot be calculated. You either need to know all three dimensions or all three dimensions must be doubled, not just one dimension (or demension / demansion as you call them).
