tolong bantu kakak bsok di kumpulin​

Answer 1

Penjelasan dengan langkah-langkah:

3. L1 (L. alas+tutup) = 2 ( a×t )/2

= 2 (6×8)/2

= 48 cm

L2(Luas sisi tegak)

• P×L=> 6 × 15 = 90
• P×L=> 8 × 15 = 120
• P×L=> 10 × 15 = 150
• total L. sisi tegak= 360 cm

Luas permukaan prisma

L1+L2 = 48 + 360

= 408 cm

4. V = π × r × r × T

= 22/7 × 35 × 35 × 120

= 462.000

5. V = L.alas × T

= 8 × 8 × 15

= 960
