Question

tolong jawab nomer 17-28 besok mau dikumpulin​

Answer 1

Jawab:

17. B

18. A

19. D

20. C

21. 8³ = 8 × 8 × 8 = 512

22. ³√729 = 9

23. V = r³

V = 12³ = 12 × 12 × 12 = 1.728 cm³

24. 30 satuan

25. 12³ + 10³ - 9³

= 1.728 + 1.000 - 729

= 1.999

26. r = ³√V

r = ³√15.625

r = 25 dm

27. p = 6 satuan

l = 4 satuan

t = 4 satuan

V = p × l × t

V = 6 × 4 × 4

V = 96 satuan

28. diket :

l = 6 cm

t = 7 cm

V = 672 cm²

ditanya : p = ?

jawab :

p = V : (l × t)

p = 672 : (6 × 7)

p = 672 : 42

p = 16 cm

semoga membantu
