V:?
Lp:
1.) volume kubus dan lp kubus
v = r³ / s³
v = 23³
v = 23 × 23 × 23
v = 529 × 23
v = 12.167 cm³
lp = 6 × s²
lp = 6 × 23²
lp = 6 × 23 × 23
lp = 3.174 cm²
2.) volume balok dan lp balok
v = p × l × t
v = 12 cm × 6 cm × 8 cm
v = 72 × 8 cm
v = 576 cm³
lp = 12 cm × 6 cm × 2 = 144
= 12 cm × 8 cm × 2 = 192
= 6 cm × 8 cm × 2 = 96
JUMLAHKAN!!!
= 144 + 192 + 96
= 336 + 96
= 432 cm²
