Answer:
15 gallons
Step-by-step explanation:
we know that
The volume of a prism is equal to
[tex]V=Bh[/tex]
where
B is the area of the base
h is the height
we have
[tex]Bh=45\ gal[/tex] ----> equation A
The volume of the cone with the same base and height is equal to
[tex]V=\frac{1}{3}Bh[/tex]
substitute equation A in the volume of the cone
[tex]V=\frac{1}{3}(45)=15\ gal[/tex]
