Answer:
B
Step-by-step explanation:
The volume (V) of the prism is calculate as
V = lbh ( l is the length, b the width and h the height )
l = h = 4 × [tex]\frac{1}{3}[/tex] = [tex]\frac{4}{3}[/tex]
b = 3 × [tex]\frac{1}{3}[/tex] = 1, thus
V = [tex]\frac{4}{3}[/tex] × 1 × [tex]\frac{4}{3}[/tex] = [tex]\frac{16}{9}[/tex] ft³
