Penjelasan dengan langkah-langkah:
v = v.balok + v.kubus
v = (p×l×t) + s³
v = (30 × 12 × 5) + 15³
v = (360 × 5) + 3.375
v = 1.800 + 3.375
v = 5.175 cm³
Jawaban
Diketahui
Panjang Balok = 30 cm
Lebar Balok = 12 cm
Tinggi Balok = 5 cm
Rusuk kubus = 1/2 × Panjang Balok
Rusuk kubus = 1/2 × 30
Rusuk kubus = 30 : 2
Rusuk kubus = 15 cm
Ditanya
Berapakah volume gabungan kedua bangun tersebut ?
Dijawab
V. kubus = s × s × s
V. kubus = 15 × 15 × 15
V. kubus = 225 × 15
V. kubus = 3.375 cm³
V. Balok = P × L × T
V. Balok = 30 × 12 × 5
V. Balok = 360 × 5
V. Balok = 1.800 cm³
V. gabungan = V. kubus + V. Balok
V. gabungan = 3.375 + 1.800
V. gabungan = 5.175 cm³
