12 tbsp of olive oil

306.9

Step-by-step explanation:

The equation for the volume of a right triangular prism is to (this is for the base of the triangle) multiply the base by the height and then by 1/2. This will determine the area. Then take the height of the whole prism and multiply that to the base's area. That will give you the volume. So in your case: 9 times 6.2 times 1/2 equals 27.9. Then multiply 27.9 by 11 to get 306.9. I hope this helps!
