Question

balok memiliki p = 20 cm, l = 12 cm, dan t = 10 cm. Tentukan luas permukaanya!



dibantu ya kak kalau bisa,, terimakasih^^​

Answer 1

Jawaban:

1.120 cm²

Penjelasan dengan langkah-langkah:

Lp = 2 × (pl + pt + lt)

LP = 2 × [(20 × 12) + (20 × 10) + (12 × 10)]

Lp = 2 × (240 + 200 + 120)

Lp = 2 × 560

Lp = 1.120 cm²

Answer 2

Verified answer

Jawaban:

Luas permukaan balok

• p = 20 cm
• l = 12 cm
• t = 10 cm

Luas = 2(p × l) + (p × t) + (l × t)

Luas = 2(20 × 12) + (20 × 10) + (12 × 10)

Luas = 2(240 + 200 + 120)

Luas = 2(560)

Luas = 1.120 cm²

Luas permukaan balok 1.120 cm²
