5. 7

6. Lp = 1.014 cm²

7. Lp = 1.144 cm²

8. V = 1.500 cm³

9. V = 1.570 cm³

10. V = 452.160 cm³

Penjelasan dengan langkah-langkah:

4. jumlah sisi prisma segi-n = n + 2

segi 8 = 8 + 2 = 10

5. banyak titik sudut limas segi-n = n + 1

limas segi 6 = 6 + 1 = 7

6. Lp = 6 x s² = 6 x 13²

= 6 x 169 = 1.014

7. Lp = Ls + La = (2 x phi x r x t) + (phi x r²)

= (2 × 22/7 × 14 x 6) + (22/7 x 14²)

= 528 + 616 = 1.144

8. V = (La x t) ÷ 3 = (300 × 15) ÷ 3

= 1.500

9. V = (phi x r² x t) ÷ 3 = (3,14 x 10² x 15) ÷ 3

= 1.570

10. V = 1/2 x 4/3 × phi x r³ = 1/2 x 4/3 × 3,14 x 60³

= 452.160
