Bangun Ruang Kubus
Panjang sisi (s) Kubus = Lebar Balok = 3 cm
Volume Kubus = s x s x s
Volume Kubus = 3 x 3 x 3
Volume Kubus = 27 cm 3 4 cm
Volume Gabungan
Volume Gabungan = V.Balok + V.Kubus 3 cm
3
Volume Gabungan = 120 cm + 27 cm 3 10 cm
Volume Gabungan = 147 cm 3
8. Jawab A
r = 10 cm
t = 28 cm
2
Volume Tabung = π x r x t 28 cm
2
Volume Tabung = 227 x 10 x 28
Volume Tabung = 8800 cm³
9. Jawab C 10 cm
diameter (d) = 14 cm
jari-jari (r) = 1/2 x diameter = 1/2 x 14 cm = 7 cm
tinggi (t) = 9 cm
2
Volume Tabung = π x r x t
2
Volume Tabung = 22/7 x 7 x 9
Volume Tabung = 1386 cm³ 9 cm
10. Jawab D
luas penampang = 154 cm 2
t = 200 cm 14 cm
Volume Tabung = luas penampang x t
Volume Tabung = 154 x 200
Volume Tabung = 30.800 cm³ 44
