Answer:
2 ft³
Step-by-step explanation:
The volume (V) of the triangular pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the perpendicular height )
A = [tex]\frac{1}{2}[/tex] × 2 × 2 = 2 ft² ← area of triangular base and h = 3, thus
V = [tex]\frac{1}{3}[/tex] × 2 × 3 = 2 ft³
