Question bank/JEE Main/Chemistry

Finely divided catalyst has greater surface area and has greater
catalytic activity than the compact solid. If a total surface area of
6291456 cm2 is required for adsorption in a catalyzed gaseous reaction,
then how many splits should be made to a cube of exactly 1 cm in length
to achieve required surface area.
(Given: One split of a cube gives eight cubes of same size)
