tolong jawab ya kakak
Jawaban:
1. Vl = V balok u
= p × l × t
= 15 × 8 × 6 cm
= 720 cm
Vll = V balok b
= p × l × t
= (15 - 5 - 5) × 8 × 3cm
= 5 × 24 cm
= 120 cm
V s keliling = Vl - Vll
= 720 - 120
= 600 cm
2. Vl = V balok
= p × l × t
= 8 × 4 × 2 cm
= 64
Vl = V balok
= p × l × t
= 8 × 4 × 2 cm
= 64
V gabungan = Vl + Vll
= 64 + 64
= 128 cm
3. Vl = V balok
= p × l × t
= 8 × 4 × 5 cm
= 160
Vll = V kubus
= s × s × s
= 5 × 5 × 5
= 125
V gabungan = Vl + Vll
= 160 + 125
= 285 cm
