Answer:

72 cm³

Step-by-step explanation:

  • The formula to find the volume of a trianglular based pyramid is [tex]V=\frac{1}{3}bh[/tex], where V is the volume, b is the area of the vase, and h is the vertical height
  • Substitute in the values
  • [tex]V=\frac{1}{3}\times (\frac{1}{2}\times 12\times 4)\times 9 = \frac{1}{3}\times 48\times 9 = \frac{1}{2}\times 48\times 3 = 72[/tex]
