Answer:
The volume of the prism is [tex]247.5\ mm^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the rectangular prism is equal to
[tex]V=Bh[/tex]
where
B is the area of the base of the prism
h is the height of the prism
we have
[tex]B=45\ mm^{2}[/tex]
[tex]h=5\frac{1}{2}\ in=\frac{5*2+1}{2}=\frac{11}{2}\ in[/tex]
substitute the values and solve for V
[tex]V=(45)(\frac{11}{2})=247.5\ mm^{3}[/tex]
