Answer:
216km
Explanation:
The formula for finding the volume of a triangular prims is:
0.5 * b * h * length, where b is the length of the base of the triangle, h is the height of the triangle and length is prism length.
So, let's substitute those variables with the base length, height length, and prism length
The base length is 6km, the height length is 8km, and the prism length is 9km
So, we get:
0.5 * 6 * 8 * 9
= 1/2 * 6 * 8 * 9
= 1/2 * 48 * 9
= 1/2 * 432
= 216
The volume of this prism is 216km.
