Answer:

[see below]

Step-by-step explanation:

Volume of a triangular prism is: $V=\frac{1}{2}bhl$

We are given the base of 5, the length of 12, and the height of 8. All measurements are in meters.

$V=\frac{1}{2}(5*12*8)\\\\V=\frac{1}{2}(480)\\\\V=240$

The volume of the prism should be 240 square meters.
