The normalized wavefunction for a particle trapped in a 3-dimensional box of dimensions 0 < x < a, 0 < y < b, 0 < z < c, is given by
Ïx,y,z = (2/a)^(1/2) (2/b)^(1/2) (2/c)^(1/2) sin (nx pi y/b) sin (ny pi y/b) sin (nz pi z/c)
For the case in which a = b = c = 10 AÌ approximate the probability that an electron will be found in a volume element whose dimensions are Îx = Îy = Îz = 0.01 AÌ and whose center is at x = 2 AÌ, y = 3 AÌ, z = 5 AÌ for the three states

*HINT: â xâ yâ z ÏâÏ dx dy dz is the probability. When the argument ÏâÏ is nearly constant over xyz
the range it can be removed from the integral and the probability approximated as ÏâÏ ÎxÎyÎz.
