Answer:
Volume of triangular Prism =Area of base × Height
As, Base of triangle = 5 ft
Height of triangle = 3 ft
Area of Base
[tex]=\frac{1}{2}*{\text{Base}}*{\text{height}}\\\\=\frac{1}{2}*5*3\\\\=7.5 ft^2[/tex]
Height of Prism =7.5 ft
Volume of triangular Prism =7.5 × 7.5
= 56.25 ft³
= 56 ft³
Option A: 56 ft³
