Tolong jawab yaa buat besok

3. = V = 9cm x 5cm x 2cm = 90 cm^3

4. = V = 8cm x 5cm x 6cm = 240 cm^3

5. = V = 1.728 cm^3 = 12cm x 12cm x 12cm = 1.728 = b = 12 cm

6. = V =720 cm^3 = 15cm x 6cm x 8cm = 720 = L = 6cm

7. = V = 540 cm^3 = 18cm x 10cm x 3cm = 540 = P = 18cm

8. = bangun 1 = 9cm x 9cm x 9cm = 729 cm^3
= bangun 2 = 9cm x 12cm x 4cm = 432 cm^3
= 729 cm^3 + 432 cm^3 = 1.161 cm^3

9. = bangun 1 = 8cm x 8cm x 8cm =512 cm^3
= bangun 2 = 16cm x 8cm x 5cm = 640 cm^3
= 512 cm^ 3 + 640 cm^3 = 1.152 cm^3

10. = bangun 1 = 12cm x 8cm x 10cm = 960 cm^3
= bangun 2 = 20cm x 12cm x 12cm = 2.880 cm^3
= 960 cm^ + 2.880 cm^3 = 3.840 cm^3
