Ni yang kalo bisa pake carany ya kalo bisa terima kasih

1.) L = 22/7 × 7 × 7 = 154 cm²
2.) V = 22/7 × 14 × 14 × 20 = 12.320 cm³
3.) L¹ = 38 × 9 = 342 cm²
L² = 19 × 4 = 76 cm²

L = L¹ - L² = 342 - 76 = 266 cm²
4.) V = 1/2 × 8 × 10 × 20 = 800 cm² = 8 dm²
5.) L¹ = 10 × 15 = 150 dm²
L² = 1/2 × 10 × 10 = 50 dm²

L = L¹ + L² = 150 + 50 = 200 dm²
6.) t = 3080 ÷ 154 = 20 dm

semoga membantu
