ANSWER
Vol. of 4cm cube =(4)3cm3 =64cm3
Vol. of 1cm cube =(1)3cm3 =1cm3
Total no. of 1cm cubes $$= \dfrac {Vol. of \ 4 \ cm \ cube }{Vol. \ of \ 1 \ cm \ cube} $$
=164
=64
Surface area of 1 cube =6(side)2cm2
Surface area of 1 cube =6(1)2cm2
Surface area of 1 cube =6cm2
Total surface area of all small cubes =64×6cm2
=384cm2
