They do not have well defined outer boundaries, so there is no firm number. Approximate size can be inferred from collision data. The "classical" electron radius is 2.8*10^-13 cm. That makes its approximate "area" about 10^-25 cm^2
The neutron-proton collision cross section is about 0.3*10^-24 cm^2
The 3/2 power of those numbers is an approximate volume.
