Expert Answer:

2.
Volume of each cube = 33 = 27 cm3
Volume of 64 cubes = 27 x 64 = 1728 cm3
Therefore, capacity of cubical box = 1728 cm3
therefore L e n g t h space o f space s i d e space o f space t h e space c u b i c a l space b o x space equals cube root of 1728 equals 12 c m
H e n c e comma space t h e space l e n g t h space o f space t h e space s i d e space i f space t h e space c u b i c a l space b o x space i s space 12 space c m.
