Penyelesaian :
suatu kubus panjang rusuunya 12 cm hitunglah
a. Luas permukaan
[tex] \sf luas = 6 \times {r}^{2} [/tex]
[tex] \sf luas = 6 \times {12}^{2} [/tex]
[tex] \sf luas = 6 \times 144[/tex]
[tex] \sf luas = 864 \: {cm}^{2} [/tex]
b. Volume
[tex] \sf Volume = {r}^{3}[/tex]
[tex]\sf Volume = {12}^{3} [/tex]
[tex]\sf Volume = 12 \times 12 \times 12[/tex]
[tex]\sf Volume = 12 \times 144[/tex]
[tex]\sf Volume = 1.728 \: {cm}^{3} [/tex]
