Hi!
WHen you are finding the volume of any prism, the formula is B * h
The capital B stands for the area of the base
So what you want to do first is find the area of the base which will be found by using (b*h) / 2
3.5 * 4 = 14
14/2 = 7
Your area of the base is 7
Now multiply 7 with 3.3 to find the volume
7 * 3.3 =23.1
The volume of the triangular prism is 23.1 inches^3!
Hope this helps!
