Have a look at that shape. Take your time, there is no need to hurry. Which side of that shape is in the front? Is it the one which top left corner is the as the top left corner of the shape? Or, is it the one, which bottom right corner is the same as the bottom right corner of the shape?
Did you move your head to see the shape from a different perspective so that you can see the different sides? Did it work? Do you have a more suitable answer now than a minute before? Most probably not, but here is an interesting idea: what if I tell you that the shape is not a cube.
You were thinking about a cube, weren’t you? But it can be a two dimensional shape with lines, triangles, rectangles and other shapes. I didn’t tell you that it was a cube.
