B., I think I learned it sometime
The volume of the rectangular pyramid is 28 cubic feet.
<h3>
How to find the volume of the pyramid?</h3>
The volume of a pyramid of base B and height H is given by:
![V = (1/3)*B*H](https://tex.z-dn.net/?f=V%20%3D%20%281%2F3%29%2AB%2AH)
Here we know that the height is H = 7ft, and the base is a rectangle of 4ft by 3ft, so the area of the base is:
![B = 4ft*3t = 12ft^2](https://tex.z-dn.net/?f=B%20%3D%204ft%2A3t%20%3D%2012ft%5E2)
Then the volume of the pyramid is:
![V = (1/3)*7ft*12ft^2 = 28ft^3](https://tex.z-dn.net/?f=V%20%3D%20%281%2F3%29%2A7ft%2A12ft%5E2%20%3D%2028ft%5E3)
