About
A standard clay building block measuring about 8 inches long and weighing roughly 5 pounds.
Standard building bricks are sized so a mason can easily pick them up and position them with one hand. Dimensions vary around the world, but most common types stay close to this handheld scale, while concrete cinder blocks can weigh over 30 pounds (14 kg). Dense clay packing gives even a small stack of these blocks surprising weight.
From Wikipedia
A brick is a type of building material used to build walls, pavements, and other elements in masonry construction. Properly, the term brick denotes a unit primarily composed of clay, but it is now also used informally to denote building units made of other materials or other chemically cured construction blocks.
