I need help with the following question about electric fields and charge density

Suppose that an electric field can be expressed as E = A (In z, 1,*), when where A is a constant with the appropriate unit. a) Find the distribution of charge density in this space, p(x, y, z). b) Take the origin as the reference point, follow the path (0,0,0) - (0,0, z) - (0, y, z) - (x, y, z) to find the electric potential at point (x, y, z). (Hint: review the demonstration of line integral during the lecture, or read Example 1.9 of the textbook.)
