tolong dijawab soalnya buat besok. pake carannya

13. Bangun 1 = 28 × 28 × 28 = 21.952 cm3
Bangun 2 = 3,14 × 10 × 10 × 20 = 6.280 cm3
21.952 + 6.280 = 28.232 cm3

14. Bangun 1 = 3,14 × 5 × 5 × 14 = 1.099 cm3
Bangun 2 = 3,14 × 5 × 5 × 7 = 549,5 cm3
1.099 + 549,5 = 1.648,5 cm3

15. Bangun 1 = 7 × 6 × 5 = 210 dm3
Bangun 2 = 22/7 × 3,5 × 3,5 × 3 = 115,5 dm3
210 + 115,5 = 325,5 dm3
