The number of 1cm cubes are 64.
So total SA of all cubes is
64•6•(1)²
= 384 cm²

Volume of 4 cm cube = 4³ = 64 cm³
Volume of 1 cm cube = 1³ = 1 cm³
No. of small cubes formed from 4 cm cube = 64/1 = 64
Total surface of 1 cm small cube = 6 * 1² = 6 cm²
Therefore
Total surface area of all small cubes = 6*64 = 384 cm²
