Answer:
V = (2/9)s³
Step-by-step explanation:
The general formula for the volume of a pyramid is:
V = (1/3)(base area)(height).
Here, the length of a side of the square base is s, and so the area is A = s². For the height we use (2/3)s. Then the volume of the pyramid is:
V = (1/3)(s²)(2/3)s, or V = (2/9)s³
