caranya please bsk dikumpulin

30)
• Volume bangun 1
= s x s x s
= 40 cm x 40 cm x 40 cm
= 64.000 cm³
• Volume bangun 2
= π x r x r x t
= 3,14 x 20 cm x 20 cm x 60 cm
= 3,14 x 24.000 cm³
= 75.360 cm³
• Volume bangun 1 + bangun 2
= 64.000 cm³ + 75.360 cm³
= C. 139.360 cm³

Maaf kalau salah:)
Semoga membantu:D
