Answer:

447 cm³

Step-by-step explanation:

Finding volume of cuboid :-

  • V = 12 cm * 4.5 cm * 5.5 cm
  • V = 297 cm³

Finding volume of triangle :-

  • V = 1/2 × base area × height
  • V = 1/2 * 12cm * 5cm * 5cm
  • V = 6cm * 25cm²
  • V = 150 cm³

Net Volume :-

  • V = 297 cm³ + 150cm³
  • V = 447 cm³
