Explanation / Answer

a) mass of 1 cm^3 of cupper = 8.92 * 10-3 kg (from density= mass/volume equation)

therefore number of atom = 8.92*10-3 / 2.51*10-25 = 3.554*1022

b) let's take number of small cube = N, then;

N*3.554*22=1 cm3

therefore N= 2.8*10-23 cm3

c) edge dimension= 3.04*10-8 m (cubic root of N)
