CUBE COUNT

How many individual cubes are there in the structure on the left? It was created from a solid 5x4x4 arrangement of cubes (shown right), and you should assume that all ‘hidden’ cubes are present (in other words, there are no ‘floating’ cubes or gaps, unseen in our illustration).

TOTAL CUBES = 48

Counting the top layer as level 1, this is made up of:

Level 1 = 5 cubes

Level 2 = 11 cubes

Level 3 = 15 cubes

Level 4 = 17 cubes
