Answer:
The volume of the mailbox is [tex]936\ in^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the prism (mailbox) 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=52\ in^{2}[/tex]
[tex]h=18\ in[/tex]
substitute
[tex]V=52(18)=936\ in^{3}[/tex]
