Question 896172
Say you have a cubic meter.
You can look at one face of this cube and
think of it as a wall of smaller cubes each of
which is 1 cm^3
-------------------
There are {{{ 100*100 = 10^4 }}} of these little
cubes in the wall.
------------------
To fill up the whole cubic meter, you need 
{{{ 100 }}} of these walls, so you then have
{{{ 100*100*100 = 10^6 }}} cm^3 in the 
cubic meter
---------------
Hope this helps
