A shape that has six faces, 12 edges and eight vertices is a cube.
According to Wikipedia the cube has "has 11 nets, which means there are 11 ways to flatten a hollow cube by cutting 7 edges. To color the cube so that no two adjacent faces have the same color, one would need at least 3 colors."
When working out questions like this it can be quite baffling if you can't picture it in your head. Therefore it is a good idea to look around where you are for shapes that it may be.
There are lots of rectangular, square and even triangular shapes in most rooms and buildings and so if you memorise the description again and then try and count the faces, edges and vertices, you should find it easy to find the correct shape.
If you were to describe a pyramid then you would say it is a shape that has five faces, eight edges and five vertices.
Like many difficult questions the key is to take time to really digest the question and think about possible answers. You can then go about ruling each shape out until you have found the one you are after.
