°•°Jawaban
Luas = 516 cm²
Volume = 720 cm³
>>Penjelasan
Rumus luas Balok
☆ L = 2x (pl+pt+lt) ☆
[tex]l = 2 \times ((15 \times 6) + (15 \times 8) + (6 \times 8))[/tex]
[tex]l = 2 \times (90 + 120 + 48)[/tex]
[tex]l = 2 \times 258[/tex]
[tex]l = 516 \: {cm}^{2} [/tex]
Rumus Volume Balok
☆ V = p x l x t ☆
[tex]v = 15 \times 6 \times 8[/tex]
[tex]v = 720 \: {cm}^{3} [/tex]

=> kesimpulan :
Jadi, luas dan volume balok tersebut adalah 516 cm² dan 720 cm³
