we know that
The volume of the prism is equal to
[tex] V=B*h [/tex]
where
B is the area of the base
h is the height
in this problem
area of the base B is the area of a rectangle
[tex] B=12*9=108\ cm^{2} [/tex]
[tex] h=6\ cm [/tex] ----------> is the distance perpendicular to the base
Find the volume of the prism
[tex] V=108*6=648\ cm^{3} [/tex]
therefore
the answer is
the volume of the prism is [tex] 648\ cm^{3} [/tex]
