Tolong bantu dong Kak nomor 11-15 mau dikumpul nih kk​

Jawaban:

11. 5dm

12. 4dm

13. 400cm²

14. 1m

15. 5dm

Penjelasan dengan langkah-langkah:

11. Vbalok = p x l x t

360 liter = 12dm x 6dm x t

t = 360dm³ : (12dm x 6dm) = 360dm³ : 72dm

t = 5 dm

12. Vbalok= Vkubus = r³ = (6 dm)³ = 216 dm³

Vbalok = p x l x t

216 liter = 9dm x 6dm x t

t = 216dm³ : (9dm x 6dm) = 216dm³ : 54dm² = 4dm

13. p = 14cm, l = 8cm, t = 4cm

Lp balok = 2 (pl x pt x lt) = 2 (14.8 + 14.4 + 8.4)

= 2 (112 + 56 + 32) = 2 (200) = 400cm²

14. Vbalok = 3.000liter = 3.000dm³ = 3m³

Vbalok = p x l x t

3m³ = 2,5m x 1,2 m x t

t = 3m³ : (2,5m x 1,2m) = 3m³ : 3m² = 1m

15. Vbalok = 360liter

Vbalok = p x l x t

360liter = 12dm x 6dm x t

t = 360dm³ : (12dm x 6dm) = 360dm³ : 72dm² = 5dm
