Answer:
The volume of the prism is 300 cubic inches not 300 square inches
Step-by-step explanation:
we know that
The volume of the prism is equal to
[tex]V=Bh[/tex]
where
B is the area of the base
h is the height of the prism
we have
[tex]B=20\ in^2\\h=15\ in[/tex]
substitute
[tex]V=20(15)=300\ in^3[/tex]
therefore
The volume of the prism is 300 cubic inches not 300 square inches
