註釋This illustrated book examines everything having to do with the square. It begins with a basic definition of the square and continues by giving some examples of squares and other interesting historical information. Some ideas addressed include why cities are laid out in square blocks, how buildings are designed from squares and cubes, and how prisms and antiprisms can be used in experiments. Fun activities such as brain-teasers, square mazes, and how to blow a cube-shaped bubble are offered. Additional topics include folding a square, drawing a square, calculating the area of a square, square multiplication, squaring off, square numbers, and constructing cuboctahedrons. (AIM)
