Answer:
[tex]\large\boxed{V=75\ in^3}[/tex]
Step-by-step explanation:
The formula ogf a volume of a pyramid:
[tex]V=\dfrac{1}{3}BH[/tex]
B - area of a base
H - height
We have a base length a = 5 in and a height H = 9 in.
In the base we have a square. The formula of an area of a square is:
[tex]B=a^2[/tex]
Substitute:
[tex]B=5^2=25\ in^2[/tex]
Calculate the volume:
[tex]V=\dfrac{1}{3}(25)(9)=(25)(3)=75\ in^3[/tex]
