Activity 12.2
Build cubes from blocks and find how many you need each time
What you need
Sixty or more identical small cubes: sugar lumps, dice, small blocks, or paper cubes folded from nets.
Method
Build 1 by 1 by 1, then 2 by 2 by 2, then 3 by 3 by 3, counting the blocks each time.
The question to answer
Alongside the cube count, record the square number for the same side. Compare how differently the two columns grow.
