    In the cube there are 10 layers or plates. Each plate is the tenth part of the cube: 1/10 = 0.1.1.
    A cube has 10 layers; 1 unit = 10 tenths.
    The cube has 100 columns or strips. Each strip is the hundredth part of the cube: 1/100 = 0.01.
    A cube has 100 strips; 1 unit = 100 hundredth.
    Each plate has 10 strips: 1 tenth = 10/100.
    The cube is composed of 1000 cubes. Each cube is the thousandth part of the cube: 1/1000 = 0.001.

    1 unit = 1000 thousandths
    1 unit = 10 tenths, 1 tenth = 10 hundredths, 1 hundredth = 10 thousandths.
