Answer:
<h2>V = 605 in³</h2>
Step-by-step explanation:
The formula of a volume of a pyramid:
![V=\dfrac{1}{3}BH](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7DBH)
B - area of a base
H - height
We have the square in the base with side length a = 11 in.
Area of a base:
![B=11^2=121\ in^2](https://tex.z-dn.net/?f=B%3D11%5E2%3D121%5C%20in%5E2)
Calculate the volume:
![V=\dfrac{1}{3\!\!\!\!\diagup_1}(121)(15\!\!\!\!\!\diagup^5)=(1)(121)(5)=605\ in^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%5C%21%5C%21%5C%21%5C%21%5Cdiagup_1%7D%28121%29%2815%5C%21%5C%21%5C%21%5C%21%5C%21%5Cdiagup%5E5%29%3D%281%29%28121%29%285%29%3D605%5C%20in%5E3)
Answer:
6250
Step-by-step explanation:
75*75 =5625
25*25= 625
add 5625 + 625 = 6250
