JAWABAN
Sebuah bangun berbentuk kubus memiliki panjang sisi 20 cm. Luas jaring-jaring bangun tersebut adalah 2.400 cm²
Diketahui :
- Sisi = 20 cm
Ditanya :
- Luas ?
Dijawab :
→ Luas = 6 × s²
→ Luas = 6 × sisi × sisi
→ Luas = 6 × 20 cm × 20 cm
→ Luas = 120 cm × 20 cm
→ Luas = 2.400 cm²
Kesimpulan :
- Jadi, luas jaring-jaring bangun tersebut adalah 2.400 cm²

= 6 × s²
= 6 × 20²
= 6 × 400 cm²
= 2.400 cm²
