How they called the pyramid is perpendicular distance between the vertex and bases?

The perpendicular distance between the vertex of a pyramid and its base is called the "height" of the pyramid. This height is crucial for calculating the volume of the pyramid, which is given by the formula ( V = \frac{1}{3} \times \text{Base Area} \times \text{Height} ). The height is always measured at a right angle from the vertex to the base.
