= 2 x () + 20(12 + 5 + 13)
= 60 + 20(30)
= 60 + 600
= 660 cm²
Semoga membantu
= 1/2 × 60 cm² × 2
= 60 cm²
L sisi = (p₁ × l₁) + (p₂ × l₂) + (p₃ × l₃)
= (20 cm × 12 cm) + (20 cm × 5 cm) + (20 cm × 13 cm)
= 240 cm² + 100 cm² + 260 cm²
= 600 cm²
L permukaan = L penutup + L sisi
= 60 cm² + 600 cm²
= 660 cm²
Semoga membantu ^^
