Jawaban:
2.205 cm³
Penjelasan dengan langkah-langkah:
• Volume balok
= p × l × t
= 15 cm × 14 cm × 5 cm
= 210 cm² × 5 cm
= 1.050 cm³
• Volume setengah tabung
[tex] = \frac{1}{2} \times \pi \times {r}^{2} \times t[/tex]
[tex] = \frac{1}{2} \times \pi \times ( \frac{1}{2} \times l. \: balok) \times p. \: balok[/tex]
[tex] = \frac{1}{2} \times \frac{22}{7} \times {( \frac{1}{2} \times 14 \: cm) }^{2} \times 15 \: cm[/tex]
[tex] = \frac{1}{2} \times \frac{22}{7} \times {7}^{2} cm \times 15 \: cm[/tex]
[tex] = \frac{1}{2} \times \frac{22}{7} \times 49 \: {cm}^{2} \times 15 \: cm[/tex]
[tex] = 11 \times 7 \: {cm}^{2} \times 15 \: cm[/tex]
= 1.155 cm³
• Volume gabungan
= V. balok + V. setengah tabung
= 1.050 cm³ + 1.155 cm³
= 2.205 cm³
