Answer:
2nd option
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h is its height )
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 30, h = 8 , then
A = [tex]\frac{1}{2}[/tex] × 30 × 8 = 15 × 8 = 120 in²
with h = 15 , then
V = 120 × 15 = 1800 in³
