How many small cubes with edge cubes of 20cm each can be just accommodated in a cubical box of 2m edge?
Volume of cube = (side)3
Volume of each small cube = 203 = 8000cm3
= 0.008m3
Now, volume of the cubical box = 23 = 8m3
Number of small cubes, that can just be accommodated in the cubical box
= 
= 1000
