Answer:
72 cm³
Step-by-step explanation:
We can use the formula for a triangle prism's volume to solve.
V = [tex]\frac{B*H*L}{2}[/tex]
-> B is the base, H is the height, L is the length
-> Think of the area of a triangle. It is the same formula, but we also multiply by the length.
V = [tex]\frac{B*H*L}{2}[/tex]
V = [tex]\frac{3*4*12}{2}[/tex]
V = [tex]\frac{144}{2}[/tex]
V = 72
