TOLONG BANTUUU DONGK BUTUHH BANGETT
Penjelasan dengan langkah-langkah:
Contoh Soal
1. Bidang Diagonal
2. Panjang kawat = 12 × 5 = 60 cm
3. Lp kubus = 6 × 10² = 600 cm²
4. Volume = 8³ = 512 cm³
5. Volume = 120 × 60 × 40
= 7.200 × 40
= 288.000 cm³
Latihan Soal
1) B
Lp = 2 × (14×7 + 14×8 + 7×8)
Lp = 2 × (98 + 112+ 56)
Lp = 2 × 266
Lp = 532 cm²
2) D
Prisma ∆
rusuk = 3×3 = 9 ✔
sudut = 2×3 = 6
sisi = 2 + 3 = 5
3) A
Limas ∆
rusuk = 2×3 = 6
sudut = 1 + 3 = 4
sisi = 1 + 3 = 4 ✔
4) D
Volume = 100 × 12/3
Volume = 100 × 4
Volume = 400 cm³
5) C
Lp = 2×8 × 10 + 2 × (10 + 8) × 15
Lp = 160 + 540
Lp = 700 cm²
