Hello!
.
The answer to your question is 495 ways.
.
n = 12
r = 4
.
nCr = n1 / (n-r)! r1
12C4 = 12! / (12-4)! 4!
12C4 = 12x11x10x9x8! / 8! 4!
12C4 = 11880 / 24
12C4 = 495

density =mass/Volume
but Si unit of volume is m3
convert 980000cm3 into m3 by dividing with 1000000= 980000/1000000= 0.098 m3
D= M/V = 65.8/0.098= 671.43 kg/m3
