The total surface area of a cube with edge 'a' is given by
.
If edge is doubled, then the edge '2a' in the above formula and so the new total surface area is
i.e. 4 times original total surface area.
If edge is trebled, then the edge '3a' in the above formula and so the new total surface area is
i.e. 9 times original total surface area.
If edge is halved, then the edge in the above formula and so the new total surface area is
i.e. one-fourth original total surface area.
