Ok a dot is 1 dimensional so no formula since no area or length but, for 1 dimension, length = x cm (in x-axis) and y-cm (in y-axis), for 2 dimension area = length * width, for 3 dimension volume = length * width * breadth but for 4th dimension time is not a physical but rather a metaphysical quantity that helps keep track of changes occuring in a given space over "period of times"
