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
