Hitunglah volume bangun ruang pada gambar di atas!

<p>Jawab: 6240 cm^3.</p><p>Pembahasan:</p><p>Ingat!</p><p>Volume balok = panjang ×lebar × tinggi.</p><p>Perhatikan gambar berikut!</p><p>Gambar di atas terdiri dari 3 balok.</p><p>Langkah 1. Menentukan volume balok 1.</p><p>Balok 1 memiliki panjang 40 cm, lebar 18 cm, dan tinggi 6 cm.</p><p>&nbsp;Volume balok 1 = 40×18×6</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 4320</p><p>Volume balok 1 adalah 4320 cm³.</p><p>Langkah 2. Menentukan volume balok 2.</p><p>Balok 2 memiliki panjang 16 cm, lebar 10 cm, dan tinggi 4 cm.</p><p>Volume balok 2 = 16×10×4</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 640</p><p>Volume balok 2 adalah &nbsp;640 cm³.</p><p>Langkah 3. Menentukan volume balok 3.</p><p>Balok 3 memiliki panjang 40, cm, lebar 8 cm, dan tinggi 4 cm.</p><p>Volume balok 3 = 40×8×4</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 1280</p><p>Volume balok 3 adalah 1280 cm³.</p><p>Langkah 4. Menentukan volume bangun ruang.</p><p>Volume bangun ruang = vol. balok 1 + vol. balok 2 + vol. balok 3</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 4320+640+1280</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 6240</p><p>Sehingga, volume bangun ruang di atas adalah 6.240 cm³.</p><p>&nbsp;</p><p><strong><u>Jadi, jawaban yang benar adalah 6240 cm</u>^<u>3</u><u>.</u></strong></p>
