From Brickipedia, the LEGO Wiki
A brick is a general term for any LEGO part. However, technically it is an element three plates or more thick, rectangular in shape, with studs on top. They often have stickers or printing on them, like many other LEGO elements. They come in many sizes, from a tiny 1x1 brick to a huge 8x8, or maybe a 1x16.
Sizes[edit source]
Bricks are referred to by their dimensions. When they are only three plates high, they can be referred to as, say a 2x2 brick. If they are taller, then a third number is added, referring to their height. An example is the 1x2x5 brick.
Interestingly enough, the only odd-number-sized bricks are the 1x and 3x sizes. All sizes above are even.
