Answer:
2.5 feet
Step-by-step explanation:
we know that
The volume of a rectangular prism is given by the formula
[tex]V=Bh[/tex]
where
B is the area of the base
h is the height
we have
[tex]V=15\ ft^3\\B=6\ ft^2[/tex]
substitute in the formula
[tex]15=6h[/tex]
solve for h
[tex]h=15/6=2.5\ ft[/tex]
