tolong jawab cara dan isinya...terima kasih
3. a, b, d
4. 5 dan 6
5. rumus prisma : luas alas × t prisma
= (½ × a × t) × t prisma
= (½ × 30 × 40) × 20
= 600 × 20 = 1200 cm³
6. rumus volume tabung = phi. r² . t
5.652 = 3,14 . r². 18
314 = 3,14r²
314 = 157/ 50 r²
157/ 50 r² = 134
r² = 100
r = 10 cm
7. rumus volume kerucut = ⅓. phi. r². t
⅓. 3,14. 10². 12
= 4 . 314 = 1256 cm³
8. volume balok = p × l × t
1785 = 105 × t
- 105 t = - 1785
t = 17 dm³
9. volume limas = ⅓ . L alas . t
64.000 = ⅓. s². 120
64.000 = 40s²
40s² = 64.000
s² = 1600
s = 40 cm
10. volume kubus = s³
29.791 = s³
31 cm = s
