Give load is uniformly distributed load.
Assuming unit width in the direction perpendicular to the plane of the paper we get load intensity (w) = 20 * 1 = 20 kN/m per unit width.
Now force at a point located at depth Z is given by,
Fz = w * Z
Therefore
Force at A = 20 * 2 = 40 kN per unit width
Force at B = 20 * (2 + 2) = 80 kN per unit width
Force at C = 20 * (2 + 2 + 1) = 100 kN per unit width.
