As the size of these particles is extraordinarily small, very many molecules are needed to form the macroscopic world (the bodies which we can see). Fore example, the number of molecules of water which fill a small glass is, approximately, one quadrillion (short scale) (1 followed by 15 zeros).

In this sequence of images we go from the inside of a nucleus of a water molecule, from near to a quark to outside the glass. From about 0.000000000000001m (15 zeros) near to the quarks to a metre from the glass.
