If a 72-candela light source is located at a distance of 3 meters from a surface, the illuminance on the surface is 8 lux.

E=I/s²
E = 72/9 = 8 lux.

The light intensity of a source is 100 candelas. The illuminance on a surface is 4 lux. The surface is 5 meters from the source.
100 = 4 x r^2 100/4 = r^2 25 = r^2 r =square root 25 = 5 meters.
