Question

The edges of a  4×4×4\ 4 × 4×4  cube are formed using blocks as shown below:



In total, 32 blocks are used.

How many blocks would be needed to make the edges of a  6×6×6\ 6 × 6 × 6  cube in the same way?

Worked Solution

Blocks in top layer = 20

Blocks in bottom layer = 20

Other blocks (pillars) = 4 × 4 = 16

∴\therefore Total blocks = 56

Specify one or more 'ANSWER' block(s) as exampled below.
Note: correctAnswer is required, the rest are optional. ("correctAnswer" is what the student would need to type in to the box to get the answer correct.)

For example:
correctAnswer: 123.40

And optionally, specify the following, but only if you need something different to the defaults: 'width' defaults to 5 if not present, and valid values are 3 to 10; 'prefix' and 'suffix' default to nothing if not present.
prefix: $
suffix: mm$^2$
