Answer:
The height of the pyramid is [tex]2.4\ ft[/tex]
Step-by-step explanation:
we know that
The volume of a square pyramid is equal to
[tex]V=\frac{1}{3}b^{2}h[/tex]
we have
[tex]V=20\ ft^{3}[/tex]
[tex]b=5\ ft[/tex]
substitute and solve for h
[tex]20=\frac{1}{3}(5)^{2}h[/tex]
[tex]60=(25)h[/tex]
[tex]h=60/(25)=2.4\ ft[/tex]
