The volume of a pyramid can be calculated using the formula V = \frac13 \times B \times h , where V is the volume, B is the area of the base, and h is the height of the pyramid. The base can be any polygon, but common shapes include squares and triangles. To find the area of the base, you need to know its specific dimensions. For example, if the base is a square with side length s , then B = s^2 . The height h is the perpendicular distance from the base to the apex of the pyramid.
