it has six faces :)
Each cube has 6 faces. So 4 cubes together would have 24 faces.
six faces
6
I think the answer is 18 becausea cube has 6 face and 3 cubes have 18 faces.
24
12
10
Each cube has 6 faces, so 6 cubes have 6 x 6= 36.
It depends on how many cubes in the stack and what shape they form.
12...?
16
