my approach.. go for the cubes which wont be on the top layer mean they wont be painted
3x9x14 mean for every side there are 2 layers exposed on opposite sides.
which means 1x7x12 = 84 cubes wont be painted.
now painted cubes = 378-84 => 294
i think m rite!!
o yeah!!!

What is the surface area of six 1cm cubes stuck together?
It depends on whether they are stuck together so as to form a 1x1x6 cuboid or a 1x2x3 cuboid, or a 1x1x2 cuboid on top of a 1x2x2 cuboid. Each of these will give a different answer.
How many cubes that each side is 2cm can the cuboid be cut into length 16 width 4 height 8?
If the dimensions of the cuboid are also in cm then (16*4*8)/(2*2*2) = 64 cubes

If you have a 10x10x10 cube made up of smaller cubes 1x1x1 cubes if you paint the outside cube how many cubes are not painted?
The entire outer layer is painted so an 8x8x8 block inside isn't painted. Zero. All cubes are painted on at least one side and the 10x10x10 cube is painted on all sides. It's a 10x10x10 cube meaning there are 1000 cubelets. Ones on the inside too. So 8x8x8 = 512.
