using FORMULA
SURFACE AREA of CUBE = 6a^2
put a=32cm for area of cube whose side is 32 we get
6×32cm×32cm = 6144cm^2
put a=4cm for area of cube whose side is 4 we get
6×4cm×4cm = 96cm^2
divide 6144 to 96 for get how many small cubes cut from big cube
6144÷96
we get 64
so we say that 64 cubes are cut from a solid cube

Step-by-step explanation:
edge of cube = 32cm
area of cube = (side ) ²
= (32)²
= 1024
number of cube = 4cm
number of 1 cube = 1024÷4
=256
