The volume of a pyramid can be calculated using the formula:
V = (1/3) * base area * height
For a pyramid with a square base with side length s, the base area is s^2 (since the base is a square with side s).
Given that the height of the pyramid is equal to the side length of the base (s), we can substitute this into the formula.
Therefore, the expression for the volume of the pyramid (V) is:
V = (1/3) * s^2 * s = (1/3) * s^3 = s^3 / 3
Hence, the correct expression for the volume of the pyramid is V = s^3 / 3, which corresponds to option E.
Therefore, the answer is:
E. V = s^3
