Answer:
B
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = area of triangular face × length
Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 6 and h = 8, thus
Area = [tex]\frac{1}{2}[/tex] × 6 × 8 = 3 × 8 = 24 units², thus
V = 24 × 20 = 480 units³ → B
