Expert Answer:

We know that, d = 

d= 8.95 g cm-3 and a = 2r (Body centre)

M= 63.54 g mol?1 a = 2 x 127.8 x 10-12 meter

n =? a = 255.6 x 10-12 = 2.556 x 10-8 cm

N°= 6.023 x 1023 a3 = 16. 6986 x 10-24

Putting the value in formula given above

n = 8.95 X 6.023 x 1023 X 16. 6986 x 10-24 / 63.54

n = 1.4166 ? 1

Therefore, copper unit is simple cubic.
