Answer:
6
Explanation:
To calculate the volume of this pyramid, you first need to find the volume of the triangular base. The formula for the area of a triangle is bh/2, where b is the length of the base and h is the length of the height. In this case, 3*4/2=6. Now, you need to multiply by the height of the pyramid and divide by 3 to get 6*3/3=6 cubic inches. Hope this helps!
