Hey there :)
We know the volume formula of triangular prism
Volume = base x height of prism
= [tex] \frac{1}{2} (base)(height)(height of prism)[/tex]
We are given:
The base = 8 in
The height = 15 in
You do not need the 17 in ( it is there to trick you )
The height of the prism = 10 in
Apply the formula,
V = [tex] \frac{1}{2} (8)(15)(10)[/tex]
= 600 in³
Your final answer will be the last option
