Answer:
V = 36 cm³
Step-by-step explanation:
The volume (V) of a prism is calculated as
V = Ah ( A is the area of the triangular end and h the height )
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 3 and h = 4 , then
A = [tex]\frac{1}{2}[/tex] × 3 × 4 = [tex]\frac{1}{2}[/tex] × 12 = 6 cm²
V = 6 × 6 = 36 cm³
