I still don't get this. We know that 1728 is the total volume of the bigger cube and the smaller cube has volume of 8 then shouldn't the answer be 216?
1728/8 = 216
So, we can cut 216 small (2 x 2 x 2) blocks from ONE large (12 x 12 x 12) block
The question asked us to find how many small blocks we can cut from SIX large blocks.
So, we need to take your answer (216) and multiply it by SIX to get 1296

How does one jump from
Cubes of 2x2x2 in a 12x12x12 cube= 6x6x6
We have 6 cubes so:
Total of cubes= 6^4=1296.
By dividing 12x12x12 (the volume of ONE large block) by 2x2x2 (the volume of 1 small block), @jpalaciosm determined that we can cut 6x6x6 (aka 216) small blocks from one large block.
So to find the number of small blocks we can cut from SIX large blocks, we must take 6x6x6 and multiply it by 6 to get 6x6x6x6
Does that help?
