I dont get theseee! HELP

Answer:
V = [tex]\frac{7}{8}[/tex] units³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the base and h the height ) , then
V = [tex]\frac{1}{2}[/tex] × 1 [tex]\frac{3}{4}[/tex] ( change mixed number to improper fraction )
= [tex]\frac{1}{2}[/tex] × [tex]\frac{7}{4}[/tex]
= [tex]\frac{1(7)}{2(4)}[/tex]
= [tex]\frac{7}{8}[/tex] units³
