Sometimes its easier to see your brick's shape if you turn on the edges, View->Show Edges. brick() takes a ton of different parameters. The normal ones are length, width and height, in Lego studs for length/width and plates for height. 1,1,3 creates a normal 1x1x1 brick. brick() is most useful for making more interesting shapes, such as when you need to plug things together in strange ways or parts are misaligned by a 1/2 brick and so on.
All studs of LEGO Bricks have the word LEGO printed on them. Not all LEGO bricks have studs, there are some which have smooth sides and are stud-less (yet these pieces will still bear the word LEGO).Stud is also some times used as a unit of measurement. Example: 2x4 means two studs wide and four studs long.
