Penjelasan dengan langkah-langkah:

2. V. Prisma

= luas alas × tinggi prisma

= 60 × 15

= 900 cm³

4. V. Tabung

= π×r²×t

= 22/7×14²×10

= 6.160 cm³

5. V. Limas segitiga

= ⅓ × luas alas × tinggi limas

= ⅓ × (½×a×t) × tinggi limas

= ⅓ × (½×9×12) × 15

= ⅓ × 54 × 15

= 270 cm³

7. V. Kubus

= s×s×s

= 24×24×24

= 13.824 cm³

8. V. Balok

= p×l×t

= 18×12×6

= 1.296 cm³

9. L. Permukaan balok

= 2×(p×l+p×t+l×t)

= 2×(20×16+20×8+16×8)

= 2×608

= 1.216 cm²

10. V. Tabung

= π×r²×t

= 3,14×5²×12

= 942 cm³

V. Kubus

= s×s×s

= 10×10×10

= 1.000 cm³

V. Gabungan = 942+1.000 = 1.942 cm³
