Answer 1

Jawaban:

25. C

26. B

27. C

28. B

Penjelasan dengan langkah-langkah:

25. V. kubus = s³

= 15³

= 3375cm³

26. V. Limas = ⅓ • La • t

= ⅓ • 60 • 18

= 360 cm³

27. d = 24 cm, t = 28 cm, π = 22/7.

V. tabung = ¾πr²t

= ¾ • 22/7 • 12 • 12 • 28

= ¾ • 22 • 12 • 12 • 4

= 9. 504 cm³

28. V. kubus = s³

= 8³

= 512

V. balok= p • l • t

= 24 • 8 • 8

= 1536

V. gabungan = V. kubus + V. balok

= 512 + 1536

= 2048 cm³
