how you done it?
there is tree integrals
in each one we go by one axes
first we got from 0 to 1 by x
so in his integral dy and dz are 0 because there is no moving on y and z axes
thats how i was tought to think.
1.is this a correct way??
2.how you made it into one integral
from a splitted 3 integrals
