Jawaban:
Diketahui
P = 12cm
L = 18cm
T = 28cm
Ditanya
Luas permukaan balok
[tex]Lp = P \times L \times T[/tex]
[tex] = 12 \times 18 \times 28[/tex]
[tex] = 216 \times 28[/tex]
[tex] = 6.048cm {}^{2} [/tex]
JAWABAN
Diketahui :
- Panjang = 12 cm
- Lebar = 18 cm
- Tinggi = 28 cm
Ditanya :
- Luas Permukaan ?
Dijawab :
» Luas Permukaan Balok «
→ Lp Balok = 2 ( pl + pt + lt )
→ Lp Balok = 2 (12×18 + 12×28 + 18×28)
→ Lp Balok = 2 ( 216 + 336 + 504 )
→ Lp Balok = 2 × 1.056
→ Lp Balok = 2.112 cm²
Kesimpulan :
- Jadi, luas permukaan balok tersebut adalah 2.112 cm²
