Kunci Jawaban Detik Detik Prediksi 4.

**20.

= 2, 23 m3 - 6000 cc + 400 l
= ( 2, 23 × 1000) dm 3 - (6000 ÷ 1000 ) dm3 + (400 × 1) dm3
= ( 2230 dm3 - 6 dm3 + 400 dm3 )
= 2714 dm 3
Jawabannya = D. 2714 dm3


**21

= Kecepatan = 45 km/jam
= Waktu = 20 Menit = 20/60 jam = 1/3 jam

JARAK = Kecepatan × Waktu = 45 km/ jam × 1/3 jam = 15 km

jawabannya = A. 15 km



**22

Debit = 90 liter/menit + 60 liter/ menit = 150 liter/menit
Volume = 18 m3 = ( 18 × 1000) liter = 18.000 liter

Waktu = Volume ÷ Debit = 18000 liter ÷ 150 liter /menit = 120 menit

Jawabannya = A. 120 menit

**28

Luas permukaan Kubus = 6 × s × s = 6 × 18 cm × 18 cm = 1944 cm2

Jawabannya = D. 1944 cm2



**29

Volume tabung = phi × r × r × t = 3,14× 15 × 15 × 40 = 3,14 × 225 × 40 = 28.260 cm3

Jawabannya = C. 28.260 cm3



**30

Volume kubus = S × S × S = 16 cm × 16 cm × 16 cm = 4.096 cm3

Volume prisma segitiga = 1/2 × a ×b ×t = 1/2 × 16 × 10 × 16 = 1.280 cm3

Volume gabungan = 4.096 + 1.280 = 5376 cm3

Jawabannya = B. 5376


**31
