we know, separation between two faces of metal cube , l = side length = 1m 
Cross sectional area of metal cube , A = (1m)² = 1m²
Force, F = 4.2 × 10^8 N
modulus of rigidity of copper, Y = 14 × 10^10 
Now, use formula, 
Young's modulus, Y = Fl/A∆l
14 × 10^10 = 4.2 × 10^8 × 1/(1 × ∆l)
∆l = 4.2 × 10^8/14 × 10^10 = 3 × 10^-3 m
So, lateral displacement of top surface, ∆l = 3 × 10^-3 m or 3mm
