Math question about geometry. (will give brainliest to whoever answers correctly with an explanation)

Answer 1

Answer:

72 cm³

Step-by-step explanation:

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