i would say A because you had to do volume=1/2*length*width*height 

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
