3
Ten 1-cubes make a 10-stick.
Start with a 1-cube. 10 Ten 1-cubes make a 10-stick. 1
4
Ten 10-sticks make a 100-slab.
5
100 10 Ten 100-slabs make a cube. 1 1000
6
So there are a thousand 1-cubes in the 1000-cube!
Ten 100-slabs make a cube. 1 So there are a thousand 1-cubes in the 1000-cube! 1000
7
...then a thousand is this big…
Watch how it builds up. × 10 10,000 100,000 If one is just this big… × 10 × 10 10 × 10 1 ...then a thousand is this big… 1,000,000 100 1,000 × 10 × 10 …and how big is a million?
8
One was just this big…. ….but a million won’t fit on the screen!
9
× 10 × 10 × 10 First the one-cube builds up to …. …a thousand-cube.
10-stick 1-cube × 10 × 10 100-slab
10
Then the thousand-cube builds up to…
…a million-cube. 1,000 1,000,000 × 10 × 10 1,000 1,000 10,000 1,000 1,000 1,000 Imagine the thousand-cube moving away, so it looks smaller and smaller…. × 10 × 10 100,000
11
Then the million–cube builds up to…
…a thousand million-cube. 1,000,000 1,000,000,000 × 10 × 10 1,000,000 1,000,000 10,000,000 1,000,000 1,000,000 1,000,000 × 10 × 10 100,000,000
12
…a million million-cube!
Then the thousand million-cube builds up to … 1,000,000,000 1,000,000,000,000 × 10 × 10 1,000,000,000 1,000,000,000 10,000,000,000 1,000,000,000 1,000,000,000 1,000,000,000 × 10 × 10 100,000,000,000
13
× 10 × 10 × 10 × 10 And so on… …from cube… …to stick… …to cube…
…to slab…
14
× 10 × 10 …to stick… …to cube… × 10 × 10 × 10 …to slab…
15
…to stick… Will it ever stop? …to cube… …to slab…
16
The cycle goes on to infinity!
…to stick… The cycle goes on to infinity! …to cube… …to slab…
