A.
jadi 432÷3 = √144. 3
jadi diagonal ruang = 12 √3
rusuk = 12 cm
b.
luas permukaan = 12.12.6= 864 cm2
c.
volume= 12.12.12= 1728 cm3

 \sqrt{432} = 12 \sqrt{3} jadi rusuk = 12 krn Panjang diagonal kubus = rusuk  \sqrt{3}
luas permukaan kubus =  s^{2} X 6 =  12^{2} X 6 = 864
volume =  s^{3}  12^{3} = 1728
