The given right pyramid with a square base has
Height = 3 inches
Base length = 5 inches
The formula for volume of a right pyramid with a square base is given as
![V=(1)/(3)* b^2* h](https://img.qammunity.org/2023/formulas/mathematics/college/75ya390tf7haleiyfgixtkr0od1q5h88ou.png)
Where
b = length of square base
h = height of pyramid
Inserting the value
It follows
![V=(1)/(3)*5^2*3](https://img.qammunity.org/2023/formulas/mathematics/college/ltx1wv5oto00q9tl3nbc9z3c6d0wpcla4q.png)
Simplifying further
![V=25in^3](https://img.qammunity.org/2023/formulas/mathematics/college/qk8j2313z9n03x2lb24sz19gb7wzz8koqn.png)
Therefore the volume of the pyramid is
![V=25in^3](https://img.qammunity.org/2023/formulas/mathematics/college/qk8j2313z9n03x2lb24sz19gb7wzz8koqn.png)
